Solving Equations
Description
The solve function solves equations. To use it, first specify some variables; then the arguments to solve are an equation (or a system of equations), together with the variables for which to solve. For example, Sage can solve the equation
(1)\begin{equation} x^2 + 3x + 2 = a \end{equation}
for $x$.
