# How do you solve 5y+13=18?

Dec 28, 2016

$\textcolor{p u r p \le}{\text{y = 1}}$

#### Explanation:

$\textcolor{\tan}{\text{Subtract 13 on both sides:}}$

$5 y + \cancel{13} = 18$
$\textcolor{w h i t e}{a a a} - \cancel{13}$ $\textcolor{w h i t e}{} - 13$

13 cancels out on the left side, and when you subtract 13 from 18 on the right you get 5:

$5 y = 5$

$\textcolor{red}{\text{Divide both sides by 5 to get y by itself.}}$

(cancel"5"y)/cancel"5"=(5)/5

Now you are just left with $y$ on the left side and 1 on the right side.

Therefore,
$\textcolor{m a \ge n t a}{\text{y = 1}}$
