Solving Simultaneous Equations

I'm presuming that something like this exists as an applet on the web, although I've never looked. I just happened into writing this and I liked it, so I posted it here.

As a schoolwide tech person, I might work this into an introductory lesson next fall (2010). Please contact me if you are interested in discussing this.

Solves two linear equations with two unknowns, graphing the lines. An Algebra II student ought to be able to expand it to do three equations.
