Math Fractional equations Fractional equation

# Fractional equation

Each fractional equation always has one or more break terms with a variable $x$, which occurs in the denominator of at least one of these break terms.

### Hint

Most often, the variable is called $x$ in fractional equations. Note, however, that even equations with other letters can be fractional equations.

### Example

• #### Fractional equation

Equations where the variable is in the denominator

$\frac8x=4$

$\frac{5x}{3x+15}+2x=10$

$\frac{25}{4x+2}=\frac{4x}{4x+2}$
• #### No fractional equations

There is no variable in the denominator

$\frac{1}{5}x+\frac{3}{4}x=8$

$\frac{2x}{2}=4$

$\frac{x+10}{4x-8}$ (No equation, only one term)
