What does Y equal?

3y=y+10

First all the variables (y) must be on one side and the numbers (10) on the other.

1. substract 1y (seen on right side of equation) from both sides of the equation:

3y-1y=y-1y+10 ------> 2y=0+10 -------> 2y=10

2. then divide both sides by two to get the y alone

(2y)/2=10/2 -----> y=5

The answer is y=5, to double check place 5 in the original equation as y

3(5)=5 + 10 -----> 15=15 check!
