# How do you solve 8= 2( s + 2) - 2?

Jul 16, 2017

$s = 3$

#### Explanation:

$\text{distribute bracket on right side of equation}$

$8 = 2 s + 4 - 2$

$\Rightarrow 8 = 2 s + 2$

$\text{subtract 2 from both sides}$

$\Rightarrow 6 = 2 s$

$\text{divide both sides by 2}$

$\Rightarrow s = 3$

$\textcolor{b l u e}{\text{As a check}}$

Substitute this value into the right side and if equal to the left side then it is the solution.

$\text{right } = 2 \left(3 + 2\right) - 2 = \left(2 \times 5\right) - 2 = 10 - 2 = 8$

$\Rightarrow s = 3 \text{ is the solution}$
