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.
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
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
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)?
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
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!!!

you just saved my life
Same bro !

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
OMG, this makes it so much easier by doing this. Thank you!
You don't understand how much this is going to help me

Thank you so much! This helped me out so much with my math homework.
I missed a few days of school and I missed the notes on how to do this so thank you very much, sir
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
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
Only 3x3? 5x5, not?
¡Muchas gracias por este video! Best one on RUclips! :))))
This is clutch. Thank you so much

😂
Sir thank you so much I truly appreciate all you do again thank you
Super video. Easy to understand!
I literally love you 😂
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
I keep getting ERR: INVALID DIM
If I could give you a million likes, I would!
thanks you!! perfectly explained

Great video thanks
tysm my teacher put down an explanation and it was completely wrong
That was amazing thank u
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 are amazing
thank you so much!!
Thank you so much
You just saved my IB
Life saver
GOAT
Update your OS.
Thank you
Thanks!!
You saved me
THANK YOOOOOUUUUUUU!!!
count the number of OKs :) ok?
Thanks
thank
I love you
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 :)
