... ax b , where the constants a ≠ 0 and b are assumed known, and we are looking for a value of x which satisfies the equation. Since a ≠ 0, the equation is easy to solve. Multiply by a −1 . Thus, we have the solution x ba . The situation is not quite so simple when we have more than one equation an ...
