Symbolically solve the equation for the expression. If there are several possible solutions (e.g. for a quadratic equation), you can specify which one you want in the third argument. Note that this argument is not optional, so you must specify 1 for a linear equation.

It is possible to solve for an arbitrary expression. This works by substituting the expression with a temporary symbol inside the equation, then solving for the symbol, and finally re-substituting the expression.

Currently iMath can only solve polynomial equations up to grade 4.

<code>EQDEF x^3 + x^2 + x + 1 = 0</code>

<code>EQDEF SOLVE(@prev@, x, 1)</code>

This will find the first solution of the cubic equation.
