# How do you add or subtract (4x)/9 + (x -10)/9?

Jul 9, 2018

Add the numerators as the denominator are the same and then remove any common factors.

#### Explanation:

$4 \frac{x}{9} + \frac{x - 10}{9} = \frac{4 x + 1 x - 10}{9}$

Combining the x terms gives

$\frac{5 x - 10}{9}$

A factor of 5 can be removed from both terms in the numerator

$\frac{5 \left(x - 2\right)}{9}$
