# How do you solve 9x+20=-16?

Jul 26, 2016

$x = - 4$

#### Explanation:

1.) First, subtract $20$ from each side.

$9 x + 20 - \textcolor{b l u e}{20} = - 16 - \textcolor{b l u e}{20}$

2.) The $20$s cancel out on the left side. Simplify the right side (add $- 16 \mathmr{and} 20$).

$9 x = - 36$

3.) Now divide out $9$ to finish isolating $x$.

(9x)/(color(green)(9)) = -36/(color(green)(9)

4.) The $9$s cancel out on the left and the right can be simplified.

$x = - 4$
