Simultaneous Equations - the Elimination Method - How to solve - Math Lesson

[@Dave251061]

I've been following your stuff for a while now. Wish I had you as a teacher mid 70s era LOL. All your stuff brings back memories and reminds me what I've forgotten. :-)... Your teaching methods are very easy and simple. ;-)

[@onlinecsk]

Yes, you are right! Even I too follow to make new sessions.

[@pumpjack2182]

yea I learn more in 15 mins than in a 45min period

[@mohdashrafali7711]

Welcome🎉

[@LURRRRRRRR]

This is literally the best instructional video I have ever seen!

[@highskiilol3151]

(Unrelated comment) Hi, Josh. Your way of teaching reminds me of my grade 10 Math teacher. You really love math as much as he do and you always enthusiastically teach us Math. You encourage me more to study Math because you put your heart in teaching us more Math knowledge and tricks - those who put their hearts in teaching would never get me bored in studying and I will always appreciate them as much as I appreciate you.

[@onlinecsk]

Yes sir, you are right!

Love this. Great revision - I home school my child and need to teach this soon!

and your using your sons account? or did he just change your profile to his avatar

[@Envyxo96er]

Do you have anything that can explain inequalities? Those are my nightmare right now

[@ralphmyers5367]

When he started typing in red pen, that's when it got silly. Just subtract 18y - 4y to get 14y. And then 24 - 10 to get 14. So y = 1. When he began multiplying both sides by -1, he just made it more complicated than it needed to be.

[@Ok_okay_la]

you explained better than my teacher in a shorter time, wow😮

[@adzesikwesiwinfred9460]

You’re the best 🎉❤

Epic! Already got it lol

[@fremilaa1069]

THANK YOU SO MUCH but i do have a question thooo why did u times it by -1 i didnt get that bit at all

[@julianstrickland7998]

wait so is it always x2 for every equation?

[@jesusmusic2698]

Sir very very Good trick, hury up

[@gonkus642]

Thank you very much for this video, i was really struggling with my homework

[@davidsweeney111]

if you get both equations in the form x = something involving y, then you can say x=x so put the two equations equal to each other and solve for y, what method is this called? I think it is an easy method.

[@SomeRandomFellow]

substitution youre taking one definition of x and youre substituting it in with another definition involving x in order to eliminate them

[@davidsweeney111]

@@SomeRandomFellow ah yes, thanks mate its substitution you're right, cheers!

Sir, how to solve subtitution method?.

Find the value of X, and put it in the 2nd equation.

[@ahmedhalad8700]

@@nadehzdamamerto749 From second equation x=12-9y Then substitution in first equation of value of x Now you have equatuon in one variable y After you get the value of y you can get the value of x by substitution in any equation .

I tried the last one myself.. finally i have solved something on techmatch channel yayy 1. 6x - 3y = 3 x2 2. 4x + 5y = 16 x3 12x - 6y = 6 x-1 12x + 15y = 48 -12x +6y = -6 12x + 15y = 48 21y = 42 y = 2 ============ 6x -6 = 3 6x = 9 x = 1.5 ============= Check 9 - 6 = 3 6 + 10 = 16

[@ralphmyers5367]

You could have started out by multiply by 5 and 3 and then avoid having to multiply by -1 in a later step.

[@riordanzanelaymena4041]

Thanks

[@audemvelle7049]

I realy love it

[@Glitch_Fiend]

what about the 10 and 25?

[@ethan8459]

Thanks!!

[@huichenhc]

Oh my god how did you get x=3 can someone help

[@russelljohnson9062]

3y can only be 3(1), 3(2) or 3(3). Meaning y can only be 1,2, or 3. Easily solving the x term for the solution

[@colecole1448]

You should do another question like: 3x - 2y = 2 5x - 5y = 10 Have a go!

[@Sayakdipta]

Aye sir, Thanks.

[@MrGyges]

Hate these bloody interrupting ads

[@tecmath]

I'll have a look at their timing. Thanks for the heads up.

[@Bai_Su_Zhen]

Every time it works, ask yourself what would happen if x=1. Saves a lot of time. If it doesn't work though, don't do that.

[@onlinecsk]

Unfortunately, putting 1 every time doesn't make sense. Because X can have all the values and unless X=1, equation won't get satisfied.

[@Bai_Su_Zhen]

@@onlinecsk Well that's what I'm saying. It only makes sense if you're right. Otherwise don't do that ever.

[@sharonturner9466]

I still don't understand 😢😢😢

I can't believe it. I can solve for y mentally now that I'm 56. When I was doing college algebra our instructor had to explain it to us many times and still didn't get it, 😂
