# How do you solve 8a = -40 ?

May 19, 2018

$a = - 5$

#### Explanation:

$8 a = - 40$

first we need to isolate $a$ so let's divide both sides of the equation by 8:

$\frac{8 a}{8} = \frac{- 40}{8}$

okay $\frac{8}{8} = 1$ and $\frac{- 40}{8} = - 5$ so:

$1 \cdot a = - 5$ and $1 \cdot a$ is just $a$

so:

$a = - 5$
