I wasn't sure if linear algebra was precal or not... hopefully I posted this in the right place.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A, X and B are all matrices.

X and B are known.

AX=B

How do you find A?

2. Relevant equations

None.

3. The attempt at a solution

I know that if you needed to find X, you could construct a matrix where:

[A|B], transform to RREF, and read off the solutions which would be A, right? But since AX does not equal XA, I guess you can't do that here.

Maybe not...

Does it have something to do with matrix inverses?

I can't find this in my textbook anywhere!! Thanks in advance for any help.
