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 $x$.
