$y = 15$ $y=15$

How to solve:
$y - 7 = 8$ $y-7=8$

1.
$ycolor(red)cancel(-7)=8$
First we cancel out the $-7$ on the left hand side of the equation by adding $7$ .

2.
$y=8color(red)(+7)$
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.

Hope this helped!
