I think this is the wrong forum...
However, I know of a few websites that deal with solving equations.
Algebrahelp.com I used as a freshman in high school..they had calculators for solving things.
Also there's a tool from the website bagatrix: MyAlgebra - Solve Your Algebra Problems Online
The latter is a little more straightforward with just the answer.
Yahoo! Answers's math section is pretty good though. People always explain and it usually doesn't take that long for your questions to get answered. I'd say it's quite fast here too though.
