You don't understand how much this is going to help me
Thank you so much!!!!!!!!,&:&3&39:),$&3&2828 thank you
I missed a few days of school and I missed the notes on how to do this so thank you very much, sir
count the number of OKs :) ok?
Life saver
I love you
thanks you!! perfectly explained
tysm my teacher put down an explanation and it was completely wrong
Thank you very much. I am taking a fast-paced finite math course and I was stuck on this type of problem for several hours. I decided to go to bed and try in the morning. Yours was the second video that came up when I searched, and it worked/explained perfectly.
It seem like that there's a trivial hiccup of the final solution in your powerpoint here(since the solution in your calculator is (-2,6,-3), not (-2,6,3)). But it doesn't matter, thanks for your sharing!!!
Update your OS.
I literally love you 😂
You are amazing

Only 3x3? 5x5, not?
Thank you
Urgent please!!! How can I solve these equations: X+Y+Z=4 X^2+Y^2+Z^2=14 X^3+Y^3+Z^3=34
You saved me
i’m a junior in high school, just regular class too, no honors, no ap, why are people in college doing this 🥲
im a sophmore :)
Thank you so much! This helped me out so much with my math homework.
OMG, this makes it so much easier by doing this. Thank you!
thank you so much!!
thank
Thank you so much
Sir thank you so much I truly appreciate all you do again thank you
This is clutch. Thank you so much
If I could give you a million likes, I would!
THANK YOOOOOUUUUUUU!!!
¡Muchas gracias por este video! Best one on UA-cam! :))))
You just saved my IB
How do you know which number belongs to which variable
It’s going down a straight line, you’re essentially removing the variables and writing then down in a matrix like how they were lined up. As seen in the video
This should be a 3x4 matrix that has what the equations are equal to. I honestly think this video only teaches people how to take a long and unnecessary route to increase their chances of bombing a pre-calc test. matrix a =5,3,2,2 2,1,-1,5 1,4,2,16 rref([A]) 1,0,0,-2 0,1,0,6 0,0,1,-3 x,y,z x=-2 y=6 z=-3
indeed
@Intellektual Oyunlar where is rref
@@mons9974 if you go to MATRIX and scroll to the right where it says MATH, scroll down and you'll find rref
I think that does the Gaussian method for you
I keep getting ERR: INVALID DIM
wouldnt it be a 3 by 4? you include the answer of each variable...
No the products have to be seperate so that's what the matrices B is for to put in the forth value to get the inverse
Thanks
That was amazing thank u
Thanks!!
Thanks it’s very useful , I just have one note about the solution in your pc, the answer of the matrix is: (-2,6,-3) not (-2,6,+3) the last number in the answer’s matrix is -3 instead +3. Thanks again for you explain ^_^
any idea what i could be doing wrong? when hitting x^-1 and enter i keep getting the error singular matrix. edit: so no idea why but on a different problem this worked just fine. idk what it was about the other one it did have 3 solutions when i did it by hand
Why did you have to take the inverse of matrix A when you typed: (A^-1*B)? What do the set of answers mean when we don't take the inverse of the two matrix's and just type in: (A*B)?
😂
Thanks so much. My instructor for my math course is not a very good teacher, she s a wonderful person, but her videos are so confusing. I appreciate you taking this step by step and added the little steps on the calculator. I understand now. God bless
Super video. Easy to understand!
you just saved my life
Same bro !

Great video thanks
