Do you mean like this??

First find the inverse of your first matrix, which we'll call [A].
[A]=
and the inverse of A called [A]inv.
[A]inv=
and then matrix multiply both sides to solve for [X].
.
.
.
The problem would then look like this,
[A][X]=[B]
[A]inv[A][X]=[A]inv[B]
[I][X]=[A]inv[B]
[X]=[A]inv[B]
.
.
.
So we do the matrix multiplication,
[X]=
[X]=
