#### Literal equation solver

## What is a literal equation example?

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.

## Why do we solve literal equations?

Literal equations, simply put, are equations containing two or more variables. Your goal is to solve for just one variable with respect to others.

## What’s a literal equation?

A literal equation is an equation which consists primarily of letters. Formulas are an example of literal equations. Each variable in the equation “literally” represents an important part of the whole relationship expressed by the equation.

## What is not a literal equation?

A literal equation is an equation that contains more than one distinct variable; multiple appearances of the same variable don’t count. For instance, x2+y2=1 is a literal equation because x and y both appear in the equation. On the other hand x2+x=1 is NOT a literal equation because x is the only variable that appears.

## How do you solve rational equations?

Solve rational equations by clearing the fractions by multiplying both sides of the equation by the least common denominator (LCD).Example 1: Solve: 5x−13=1x 5 x − 1 3 = 1 x .Solution: We first make a note that x≠0 x ≠ 0 and then multiply both sides by the LCD, 3x:
