Matrix A has inverese

B= [ 2 1 3 ]

1 1 1

4 2 1

I need to find a matrix X such that XA=C, where

C= [ 1 2 3 ]

1 0 1

0 0 0

Any ideas will be helpful. Thanks

You are given that AB = BA = I, the identity matrix. You are given B and C. You are asked to solve "XA = C" for X.

. . . . .(XA)A

This leaves you with X(AA

Thanks a lot! I actually managed to solve for Y but couldn't rationalize enough to get X. It's greatly appreciated!!!
