**drwls**, Sunday, January 25, 2009 at 9:01amI could help you solve those equations, but I do not understand the matrix part of your question. You could use determinants (a matrix calculation) to solve them, but that is not necessary.

What are R1 and R2? Are your matrices supposed to be related to your set of equations?
