in reply to solving system of equations with complex expressions

Hi, how do you pass from 2x1+3x2-7x3+7x5 = 7 to [-7,2,3,-7,0,7] also the first equation seems to be wrong given you have 22 = 7. Then you show an equation with variables. I'm not clear what are you looking for: a symbolic evaluator? an equation parser? both?

Maybe if you explain your problem domain a little bit more people will be able to help you better

    It seems he meant the numbers after the x to be exponents. Move 7 over to the left side, you have

    -7*x0 + 2*x1 + 3*x2 - 7*x3 + 0*x4 +7*x5 = 0

      this is what I meant
