# How do you solve 18=9(x+5)?

Mar 15, 2018

There are several ways, but I'd probably do it as below.

The solution is $x = - 3$.

#### Explanation:

$18 = 9 \left(x + 5\right)$

Expand brackets:

$18 = 9 x + 45$

Subtract $45$ from both sides:

$9 x = 18 - 45 = - 27$

Divide both sides by $9$:

$x = - 3$
