# Calculators :: Solving Equations :: Rational Equation Solver

The following calculator can be used **solve rational equations.**
These are equations in which the unknown variable is found in the denominator.

Example 1: to solve
$\frac{1}{x} + 2x = 3$ type **1/x + 2x** and **3**.

Example 2: to solve
$\frac{10x}{x^2+5x+6} + \frac{2}{x+2} + \frac{x}{x+3} = \frac{x}{x+2}-\frac{5}{x+3}$
type **10x/(x^2 + 5x + 6) + 2/(x + 2)+x/(x + 3)** and **x/(x + 2) - 5/(x + 3)**.
