Matrix A = 8 -1
Matrix B= x y z
u v w
Answer = 49 4 24
27 12 12
I need to get the answers for x,y,z,u,v and w by using Matrix A and the already given answer, anyone understand it?

that's all? I really don't know what the exercise is trying to mean XD
Yeah all it says is find x,y,z,u,v and w. I was thinking taking the inverse of A and using it but I'm not quite sure how or if that would work.
Unless you are told that there is some relationship between A and B, that's impossible.
That's like saying "y= 4. Find x"!!
Ok, thank you!
Actually I figured it out, if you take the inverse of A and multiply it by the finished matrix you get the answer.
You forgot to give us the set-up to the problem.
