[@matthieu_fulhaber]

Guys, i actually got the following which still work: z = -4 ; y = 8 ; x = 1 all are variables which fit in the equation. Strange that the teacher did't show that there areother solutions to this...?

[@taylorharris5742]

Mr. McLogan, I passed my college placement exam because of your videos. I am a non-traditional student who lost nearly all mathematical knowledge after high school. Thank you so much for uploading all of these great videos. They have been a tremendous help. I also passed my first college-level math exam with a 90 the other day.

awesome! congrats to you

[@happygilmore8321]

he tries to make video notes like this one but they're nowhere near as good. These videos and some others like these are the only vids that are keeping me from failing

[@realdvgarg]

true that mate.

[@sadovuato]

I like how he doesn’t say unnecessary complicated stuff that we don’t need to know at all. He just says the steps and makes it easy to understand.

[@wreckim]

You make a good point. That's what this video is for. Just remember that there are other Majors where all that complicated stuff is certainly going to be needed.

[@tiff_2268]

i like that your class is interactive, my class never answers any questions because we literally don’t know what our teacher is saying

[@DetectiveConan990v3]

LOL thats rough buddy

[@phoebe7918]

Lol😢

[@gotem123]

Same here, in my class we all just kinda stare at the teacher because he explains everything so much more complicated than it needs to be.

[@NiveaKhondaker]

He's teaching me more than my Algebra 2 teacher does- and she made everyone who had her go close to failing the whole class.

[@brianmclogan]

Sorry to hear but so happy to help!!

[@tyronnepatterson2129]

Better mentor than my school teacher thank you so much ,, you don't know how much your helping the youth ....it's really hard to find a teacher that actually even seems like they care about our education and I really appreciate it ❤️

[@teambordercontrol4799]

I have expended over two hours with a rather convoluted problem for homework. I attempted to follow along with your instruction and the results were remarkable! Not only was I able to obtain the correct answer I can now elaborate on the rationale for doing what I did on this topic. You have my best regards.

[@arianieperez1139]

You have literally been the math tutor I have always needed! I wish I had you as my teacher, I would actually enjoy going to class and solving problems. These videos make my at home life so much easier!!

[@melbar4734]

My teacher didnt even show us how to do this and gave us homework on it :D Thank you so much for your ever helpful videos

[@krystigoers1517]

I love how he labeled his equations I’m gonna start doing that bc I get lost in my own work

[@VoidTheVixen3143]

I’m not even in this classroom and it was more engaging than my irl class!! Good work dude!

[@hehehehhohohoho1753]

This is the best teacher ever.

[@jasond.4882]

Absolute lifesaver. we are reviewing this in algebra 2 just for now, and i remembered how to do a regular 2 system, but forgot how to do a 3 system. i have so many after school activites and one of them cuts into my 7th period(math) which effectively cuts my learning. thank goodness this guy exists because i would be completely lost withought him

[@elisha7130]

my algebra 2 teacher doesn’t explain it correctly and this video really saved my life cause i have a test on tuesday

Im taking alg 2 trig in school and since i did alg 1 two yrs ago i kinda forgot the fundamentals lol. U help me a lot. My teacher goes rly fast and never explains his steps. Thank u for helping

[@user-gs2vw1uy5v]

although this video was published 10 years ago, it is still helping so many people including me.. thank you teacher♥

[@Luke17d]

My teacher just rushed it, didn't even go in depth. Then he let us solve it. I can honestly say 90% of the students did not understand it at all. Thank you for your teaching.

[@bettyechavarria7710]

When you multiplied equation A and B how did you come up with -5 and 2?

[@brianmclogan]

Those are the scalars that allow me when multiplied to obtain the same coefficients for y so that y can be eliminated when I combine the equations

[@Brobecreative35]

Betty Echavarria oh because basically when he did A he was multiplying a negative by negative giving him a positive, so to cancel out y he need B to be negative and positive 2 was a good solution for that

[@Jnan._.]

I had the same querie and the responses helped me a lot.Thanks:)

[@stephensargeant166]

Your still helping kids that is struggling 8 years later wow. Thanks

[@deziolivas9908]

thank you for making these videos. i always come to your channel whenever i need help. my professor isn’t the best at teaching. well, i’m sure she’s great, but i learn at a slower pace. she shows us nothing but short cuts. it confuses me. your videos help me out tremendously because you explain every single step. thank you so much!

[@glomari62]

Thank you very much. So much easier than how my lecturer explained it. Now i will be able to pass my coursework and exam.

[@starlightningduelist7273]

Thanks, I was confused in my math class and didn’t want to ask for help, you just helped me a bunch!

[@aaroncatelli5032]

Congratulations! you can teach and you actually make sense, my teacher on the other hand ehh

[@nekukool4306]

Have a test tomorrow and this video is really helping me with understanding this lesson thanks so much!

[@quinbannon918]

How’d it go

[@AL-to6lf]

How'd you come up with multiplying both equations by 3? Where'd you get the 3 from?

[@Nofux2give]

Bdhiya padhaya sir ne 👏👏👏👏

[@KamikazeeBasher]

best explanation of how to do this ive seen out of all the other youtube videos i watched, thank you!

[@Alicia-nb2sf]

Like 5 weeks into school and my teacher doesn’t teach us anything. Plus my lam class is first period so he’s always writing notes instead of teaching. Just found out I have a test on this tomorrow. I have no idea how to study and it’s worth 60 percent of my grade this is helping A LOT

[@tristanfoss7469]

In fairness to teachers, no matter how you do or describe these types of equations, they always take forever and have a lot of variables that can accidentally be screwed up. In my class, no one liked this method because even if you can understand how to do it, it still takes forever. If you're clever, you can usually come up with usable shortcuts to math, but you always have to figure out X, Y, and Z the hard way.

[@MathProfessorKyleMartin]

We do it pretty quick on my channel... just sayin 😀

[@4_GAMING]

The best teacher I have ever seen in my life!! 😮

[@CHEENATalks]

So much help!! begillien times better of a teacher then mine!

i am so happy you made this, even tho it has been eight years i am now doing distance learning because of Covid-19 and struggle with math. this made it so much easier to understand and is going to let me graduate.

[@willssnowboardclips748]

Massive thanks to this guy, allows me to mess around in class, go home, watch a 10 min video and be better off than if I payed attention

[@MathProfessorKyleMartin]

We do it even faster on my channel. Take a look if you want more time to mess around 😉 or don't... up to you, but I bet you'd like my bumper video

[@justdont_peekme]

Thank you so much my teacher overcomplicates everything, I love you.

You are awesome! You just saved my math life.. I could not for the life of me properly organize and label these problems without getting myself all lost.

[@brianmclogan]

happy to help

[@peddirao537]

solving 1+2, 1+3 would be easier because y is common for both 1st and 2nd equation. And 3z is common for 1st and 3rd equation. 2x + y + 3z = -2 x - y - z = -3. solve them by adding. You get 3x+2z=-5. Therefore, z= (-5 -3x)/2 Now, 2x + y + 3z = -2 3x - 2y +3z = -12. Solve them by subtracting. You get -x + 3y = 10. So, y=(10+x)/3 Now substitute all the values in any one of the equation: x - y - z=-3 x - (10+x)/3 - (-5-3x)/2 = -3 Therefore x=-1 y= (10+x)/3 = 3 z= (-5-3x)/2 = -1

[@afemike68]

Your videos literally save my life! Thank you!!

[@MathProfessorKyleMartin]

If you need more help, I have a bunch of similar videos but am a smaller math channel that's able to respond and help out my viewers 😀

[@shayy321]

when we did elimination for equatkon A and B we tried to cancel out 5y and 2y right? hence why we multipled the equations by -5 and 2?

[@nathanows7]

This video really helped. Thank you so much 🙏🏾. I was studying for a math test on linear systems and forgot study this, but your video made me understand it very well. I understood what to do halfway through the video 😅👍🏾

[@brianmclogan]

You are very welcome Nathan

[@Mikey-mike]

Firstly, always take the determinant of the matrix so that one doesn't waste one's time if and when the determinant is zero. Cramer's rule is the best method.

[@matthieu_fulhaber]

Guys, i actually got the following which still work: z = -4 ; y = 8 ; x = 1 all are variables which fit in the equation. Strange that the teacher did't show that there areother solutions to this...?

Thank You Mr.McLogan!!!!!

[@dianedavidson8536]

When you break the three together into two sets of two together - 1, 2, 3 into 1 & 2 and then 2 & 3 - do you have to multiply 3 times 2 for both - or could you put 3 times for one and then something else for the other? If 3 had different coefficients?
