The advantage here is that you can enter the equations in a fairly intuitive way and not have to worry about 'wiring it up' to the solver. The Excel Solver (or even maybe the new Open Office 3.0b Solver?) would be a good bet too. Maxima is really for getting analytic solutions, although it might be possible to get numerical solutions as well -- I'm not sure.
