Matrix A = 8 -1

4 -3

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"!! - Feb 26th 2013, 05:27 PMJP2012Re: Matrices
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.

Hello, JP2012!

You forgot to give us the set-up to the problem.
