thank you for teaching me in 7 minutes what my teacher couldn't in 2 weeks

[@hassanibrahim3196]

Hey..you..stop reading the comments and pay attention to her!

[@stacieball977]

😂😂 As a teacher, this got me! I needed a laugh today. Thank you!

[@kimboots1]

We did it! I homeschool my son. This was the first to stump me. You got us through it. Thank you.

[@Melon21]

how's he doing?

[@littlelady2742]

Thanks , you just taught me what I didn't understand for a month in 9 minutes. 😃

[@LukeyBro7777]

Thank you for helping me teach my son what the teacher could not.

[@alexislindsay1491]

So helpful and clear! Please do more math videos.

[@lupemoya9841]

Wish you were my teacher

Oh I get it now my brain was on vacation, time to be an honor student again😁🙏🏾😊

[@stacieball977]

This helped me more than you will ever know! 👏🏼 🤠 Thankee kindly from Houston, TX!

[@natalie10223]

You could maybe explained why you would multiply by a -10 so it made sense..otherwise great explanations thank you.

[@josephlawson9659]

I think its because its two positives

[@mdonoghue9190]

She is using the elimination method. The coefficients in the top equation are 1. She's not showing the step of multiplying the bottom equation by 1.

[@JoeCnNd]

She's eliminating D in the equation. If she wanted she could eliminate n by -5 as well. I know it's been 2 years but some others might need help.

Thank thank you thank you... my son and I are having AMI days and we were both baffled. Your video helped is TREMENDOUSLY 🎉🎊🤓🤗you are awesome... could you be our math tutor 🤗

I'm just here to say you're a life saver... ❤

wondering why my professor didnt just explain it like this in the first place so much easier thanks !!!

[@vascobishop3359]

A good lesson. Likeable teacher

[@wodeyaeric5351]

Would u pliz do more of these simultaneous equations to concretize my understanding of the whole Linear stuff?

Omg thank you so much!!! I feel like maybe I won’t fail my quiz tomorrow now!

Ur a great teacher thanks for this

excellent visualization that you provided us

You're a great teacher.

[@itsawes0me655]

I wish you were my teacher because she barely taught us a thing in this subject and now I get it

[@ddmdj5581]

omg thank u so much, i have a quiz tm and i was searching the whole internet on how to do the math. THANK U

[@Pure77]

That was awesome.

[@angeline1565]

Thank you. U saved me I was having hard time understanding this now I can solve it

[@thebigbananabigverybig921]

Thank you for the video! I forgot how to solve this for my homework!

take a shot for everytime she says ok

[@shmurda21]

I wish you were my teacher😖 I learnt so much in 12 minutes than my teacher could ever teach me in a week

[@jimstrachan8233]

Your process for solving was excellent 😂

[@mojostudios9326]

Thanks a lot. I at first didn’t see that you had to use decimals for the second equation.

[@jimstrachan8233]

Why did you use -10 in the equation when solving for how many nickels you had?

[@dormanthongjoong8873]

when you said that if you didn’t like decimals or fractions you could just multiply the whole thing by 100, does that work for every problem and afterwards do you have to put the decimal back in the equations?

[@jenniferhampton803]

yes, you can always multiply by a number to clear fraction or decimals as long as you do it to both sides. you don't have to plug back in the decimal or fraction because by multiplying BOTH SIDES (that's important) you have dealt with them and don't have to ever think about them again

[@ingredantoine9342]

Thanks Ms. Milkosky!😊

[@edeltovilla2773]

I loved the way you explained that

Thanks this was very helpful

[@eraze5734]

OH MY GOD THANK YOU SO MUCH🙌🏽

[@arroyopamela89]

How did you get -10 ?

[@JuiceyJiggy]

Pamela Arroyo she got -10 bc she wants to eliminate something with -10

[@lavaniadelrey2807]

When using systems of equations to solve, you can use the method of substitution or the method of elimination. In this example she used elimination. You use elimination to eliminate 1 variable to get the other. By multiplying the first equation by negative 10, she was able to get rid of the dimes so we could work with nickels.

[@leoou6359]

Thank you so much your video helped me a lot

[@GIMPspencer]

Wow

[@jadawilliams4187]

thanks u so much. You helped me understand it better

[@onward2727]

Is it a rule that you have to convert the decimal portion of these problems in order to solve them? Because I've tried without converting them and I get the wrong answer So you **HAVE** to convert them, right? (usually by multiplying the entire decimal portion/equation by 100). Not just if you want to?

[@vperkin69]

Where did you get the minus 10 is that suppose to be the dimes you subtracted from the nickels

[@sk1_nelly]

vperkin69 no -10 is so that you can get rid of the positive 10

[@joeysasa3819]

Why n, d and 23 is multiplied by -10? Where did 10 come from?

[@hailem3999]

How would you solve a similar question to this but only the total amount and number of coins is given, and you are asked to find the number of nickels, dimes and quarters.

[@fvbiha]

I love you like fr 😭

[@longbeachinthehouse]

Great video, I just got lost when you multiplied by -10. I don’t know why or where the -10 came from.....

[@thekoala9337]

Hey me too. Pls help uss

[@nerdlife7625]

I wana know too

[@JoeCnNd]

OK, she chose negative 10 because she wanted to eliminate the variable D. She could have also chosen -5 for the n variable to eliminate that as well.

[@izzyunlocked2868]

thank you so much, I am so glad to have finally found a good youtube math video!!

[@nalc7182]

goo0d job saved me

[@lil_Jay6510]

thanks for the video, it kinda helped but what if you not dealing with coins so you don't know the numbers in the second equation how would you find that out?

[@farheenyousuf6199]

Thanks for making it so easy

[@bluba1lz144]

I'm confused on why you picked -10 to multiply by.

[@WileChile51]

To make the coefficients of one of the variables opposites of each other so they cancel out when you add them. You could also choose to multiply by -5.

[@kyliehua2033]

Thank you so much

[@fionamollika]

this helped me so much omg

[@aaronramirez493]

Ah yes. Only one issue. I'm doing pennies, dimes, and quarters. The amount of dimes and pennies are the same, and the total amount of coins is 34. The total amount of change is $3.04.

[@vperkin69]

Also how did that 23 turn into 230

[@alienexperiment123]

she multiplied it by 10 😳

[@sacrafyce7969]

This taught me not to write down .5 for nickels. I cant believe i accidentally wrote down .5 when its .05.

[@calaburgos8716]

this was so helpful

[@nikki9259]

i’m still confused LMFAOOOOO

[@rajahalibarapangcat2231]

But the value of the nickels and dines are not given by the problem...

[@halimac2439]

Nickels are .5

[@JoeCnNd]

@@halimac2439 thats 50 cent.

[@waka9318]

Thank u so much

[@PhiferCooksJR1]

thanks, a lot!

[@tatu919]

Here is the simple way to do : Let x represents nickel . .05x +.10(23-x)= $1.55 .05x + 2.3 - .10x = 1.55 -.05x +2.3 = 1.55 -.05x =-.75 X = -.75÷ -.05 X= 15 ( X= 15 nickels) 23 coins minus 15 nickels = 8 dimes. Let's check if all those coins add up to the amount of $1.55. .05 × 15= .75 cents. .10 × 8 =.8 cents . .75$ + .8$ =$1.55

[@Edselsmellswell]

You lost me at multiplying the top equation with -10, then again in adding the two equations. Like I didn’t know we can add equations, or maybe I’ve forgotten. when do we do that and why

[@lionstribe3261]

These questions make me loose my shit when studying for the ASVAB and the questions about what number is three times this number plus five times another number i literally feel like bashing my head into the table because of math lol idk why i just can never master it

[@lyricgibson309]

4 quarters makes a dollar

[@gregdag143]

Super helpful thanks (not sarcasm)

[@billpreetsingh4090]

Can u multiply the equation by 100 every time?

[@sophiagullett654]

Yes. As long as you multiply everything in the equation by a hundred then it will equal the equation you started with (but your answer will be multiplied by a hundred) for example 5+3=8 and 500+300=800

[@neymar1062]

Numbers can't jum at you. I thought people jump at numbers

[@exoticroyalties358]

Or you could just divide the bottom equation by -5. ;)

[@tenzinmisakii5209]

I think you're wrong about the "Picky or not picky" part! The question doesn't says to solved! the question is asking how many dimes and nickles!! so after solving the equations. You are supposed to state! how many dimes and how many nickles in sentence.

[@Willthatrll]

Teach me something my teacher cant

[@neymar1062]

Of course the teacher would no what n is equal to because she will be teaching math of course. Why would you randomly go up to any person with your paper and say the answer???
