Work Step by Step
To add rational expressions with the same denominator,
add numerators and place the sum over the common denominator.
If possible, factor and simplify the result.

$\displaystyle \frac{9x}{24}+\frac{x}{24} = \displaystyle \frac{9x+x}{24}$
$=\displaystyle \frac{10x}{24}$
$=\displaystyle \frac{2(5x)}{2(12)}\qquad$... reduce by 2
$= \displaystyle \frac{5x}{12}$
