[Maxima] Simultaneous Matrix Equations

[Tim Milstead]

I wish to solve multiple simultaneous equations. Each equation is a 
matrix equation.
As an introduction I have tried solving a single matrix equation like this:

solve(matrix([x],[y])=matrix([1],[2]));

without much luck. I just get [] for the answer.
Can Maxima do this?
Can people reply to my email address in addition to the mailing list?


Thanks in advance,

Tim Milstead.
