# How do you solve (3x)/5 = 12?

Jan 8, 2016

$x = 20$

#### Explanation:

$\frac{3 x}{5} = 12$

Multiply both sides by $\textcolor{red}{5}$

$\implies \textcolor{red}{5} \cdot \frac{3 x}{5} = 12 \cdot \textcolor{red}{5}$.

$\implies 3 x = 60$

Divide both sides by $\textcolor{p u r p \le}{3}$.

$\implies \frac{3 x}{\textcolor{p u r p \le}{3}} = \frac{60}{\textcolor{p u r p \le}{3}}$

$\implies x = 20$
