The original answer is mostly taken from here : http://qr.ae/R921PM <http://qr.ae/R921PM> I am also little confused about taking difference, but since here we are going to handle only linear function. So I didn't think about this. I implemented some parts of this, here : https://github.com/sympy/sympy/pull/10713 I will discuss about diophantine solver with solveset, implement the collapsing constants paper , solve_poly_system and multivariate polynomials equation system ,after reading about them thoroughly (with some good ideas, questions) as soon as possible. I am getting some difficulty in implementation of `LambertW` in solveset. We can implement this using bivariate.py , right ? But it is handled through list and old methods.If we want this in solveset then need some good changes in file (or need to rewrite). Please share your thinking regarding this.
