# How do you solve  8+5(s-1)=18?

Jun 22, 2016

$s = 3$

#### Explanation:

To solve $8 + 5 \left(s - 1\right) = 18$

Begin by distributing the $5$ to the values inside the $\left(\right)$

$8 + 5 s - 5 = 18$

Combine like terms on the left side of the equation $8 - 5$

$5 s + 3 = 18$

Isolate the term with the variable by additive inverse

$5 s \cancel{+ 3} \cancel{- 3} = 18 - 3$

$5 s = 15$

Isolate the variable by multiplicative inverse

$\frac{\cancel{5} s}{\cancel{5}} = \frac{15}{5}$

$s = 3$
