Good freeware for solving equations symbolically

Question

Many years ago I used maple to solve equations symbolically. Are there any good freeware alternatives?

I have three equations in three unknowns and want to find the solution symbolically

Answer 1

You can look at Sage, Maxima and others for specialized fields.

See Comparison of CAS programs.

There is even a Mathematica like one called Mathics.

For example, if you are looking for Geometry, there are choices too.

By the way, for your problem, you could just try Wolfram Alpha.
