# How do you solve 12 - 4 x = 16?

Feb 14, 2016

$x = - 1$

#### Explanation:

$12 - 4 x = 16$

Subtract $12$ both sides:

$\rightarrow - 4 x = 16 - 12$

$\rightarrow - 4 x = 4$

Divide both sides by $4$

$\rightarrow \frac{- \cancel{4} x}{\cancel{4}} = \frac{\cancel{4}}{\cancel{4}}$

$\rightarrow - x = 1$

$\Rightarrow x = - 1$
