Find the 3x3 matrix X such that XA=B, where

Code (Text):

1 1 1

A= -1 0 -2

1 0 -1

1 3 0

B= -2 1 -2

1 4 -1

The attempt at a solution

I understand how to do AX=B just fine, but XA=B is confusing me. I tried doing [x y z] A, but not sure if that's even right or what to do after that. Yes, I know it can be solved using inverses or whatever, but the professor does not want us to solve it that way (haven't gone over inverses yet).

The solution for X such that AX=B involved finding individual columns, so does that mean XA=B will find the individual rows?

Any help is appreciated!
