Explanation:

How to solve:
#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.
