## What is an example of a literal equation?

A literal equation is one that has several letters or variables. Examples include the area of a circle (A=πr2) and the formula for speed (v=Dt). If the unknown variable is in the denominator, we multiply both sides by the lowest common denominator (LCD) and then continue to solve.
