    Out of the box GiNaC can solve a linear system of equations
  only. For my package I wrote a routine which is resolving a system of
  linear equations and at most one additional quadratic equation. I do
  not think my coding may serve as a model, but you can see it anyway at
  Section G.5.5 here:
