Solving For Y.
7y+2=10
7y+2-2=10-2
7y=8
7y / 7 = 8 / 7
y = 1 1/7

When solving equations, your ultimate goal is to isolate y.
7y + 2 = 10
First step: Bring the 2 over to the right hand side. Any time you do this with any number, it switches sign (in this case, it switches into -2).
7y = 10 - 2
Solve as normal.
7y = 8
Now, divide both sides by 7. This is how to get the y by itself.
7y/7 = 8/7
Note that you have fractions now, and the sevens (7s) cancel themselves out on the left hand side, leaving you with
y = 8/7
That's your answer!
