Well, would be nice, but think about the following. An algebra, which is
a field. Depending on which equations you want to solve, there is need
for completely different algorithms. Solve (ax+by=c,dx+ey=f) for x and y
or ax^2+bx+c=0 for x.
Add a new operation (diferentiation) making the algebra into a
differential field, there are even more ways to come up with equations.
Unless you specify what solver you intend to write, it's probably an
unsolvable task to write a general solver that works for all types of
algebras.
