# How do you solve \frac { - 12} { m} = 3?

Jan 16, 2018

$m = - 4$

#### Explanation:

$\text{multiply both sides of the equation by m}$

$\cancel{m} \times \frac{- 12}{\cancel{m}} = 3 m$

$\Rightarrow 3 m = - 12$

$\text{divide both sides by 3}$

$\frac{\cancel{3} m}{\cancel{3}} = \frac{- 12}{3}$

$\Rightarrow m = - 4 \text{ is the solution}$

$m = - 4$

#### Explanation:

Multiply $m$ to both sides:

$\cancel{\textcolor{red}{m}} \cdot - \frac{12}{\cancel{m}} = 3 \cdot \textcolor{red}{m}$

$- 12 = 3 m$

Divide both sides by $3$

$- \frac{12}{\textcolor{red}{3}} = \frac{\cancel{3}}{\cancel{\textcolor{red}{3}}} m$

$- 4 = m$
