Thanks for your interest in sympy. Yes, you can solve systems of equations, see here for some examples: http://wiki.sympy.org/wiki/EuroSciPy2008_examples#Linear_Solving http://wiki.sympy.org/wiki/EuroSciPy2008_examples#Nonlinear_Solving and you can use python lists, or numpy arrays (with sympy expressions in it), so I think you can do what you want. If you have problems getting this done, feel free to ask again.
