Matrix equation solver
01/01/13 10:33am

I have matrix A

{{-1, -1, 1}, {2, 3, -1}, {-3, 2, 2}}

and matrix B

{{-1, 2, -1}, {1, 2, -2}, {2, 1, -1}}

And I want find matrix X, which equation

XA-B=2X

But I don't know, how do it.

I try

Solve[XmatA - matB - 2X = 0],

but I give:

Set::write: "Tag Plus in -2\ X+XmatA+{{1,-2,1},{-1,-2,2},{-2,-1,1}} is Protected."

Solve::naqs: 0 is not a quantified system of equations and inequalities.
