# How do you solve x/(x+2)= 15/25?

Feb 16, 2016

$x = 10$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} \frac{x}{x + 2} = \frac{15}{25}$

Multiply both sides by $25 \left(x + 2\right)$
$\textcolor{w h i t e}{\text{XXX}} 25 x = 15 x + 30$

Subtract $15 x$ from both sides
$\textcolor{w h i t e}{\text{XXX}} 10 x = 30$

Divide both sides by $10$
$\textcolor{w h i t e}{\text{XXX}} x = 10$
