Program to solve system of equations

[JG89]

I need a easy-to-use (i.e. no programming, if possible) program that's free that can solve a system of equations with 6 variables and 6 equations. Any suggestions?

A TI83 calcultor will do the job if the equations are linear, but otherwise you will need to use a Computer Algebra Software, of which there is no excellent free package, although sage could do reasonably at the job you are asking about.

Thanks for the replies. I used a TI-83.

Another option for a small problem like this is Excel. You can used the matrix functions MMULT and MINVERSE.
