Hello cheetah970,

Yes, there is. I haven't tried this, but the administrator posted it a long time ago. Here is the link:
http://web2.0calc.com/questions/systems-of-equations

For the equations:
2y-3z = 4
-y + 7z = -12

You would put in something like this:
solve( 2 * y - 3 * z = 4 , - y + 7 * z = - 12)

But I tried your equation, and strangely it doesn't work. Maybe it is a typo?
Sorry I couldn't help a lot; maybe when Melody or some of the other people come on they may be able to help you:)
