# How do you solve y-7=8?

Mar 8, 2017

$y = 15$

#### Explanation:

How to solve:
$y - 7 = 8$

1.
$y \textcolor{red}{\cancel{- 7}} = 8$
First we cancel out the $- 7$ on the left hand side of the equation by adding $7$.

2.
$y = 8 \textcolor{red}{+ 7}$
If we cancel out the $- 7$ on one side by adding 7, we must then complete the equation by adding 7 to the other side.

3.
$y = 15$
Add together all like terms. In this case, we add together 7 and 8 to make 15.
