<span>3y + 53 = 7y - 55 is a three step equation. Our goal is to get 'y' by itself.

First we subtract 3y on both sides of the equation.

</span>3y + 53 = 7y - 55
-3y          -3y

53 = 4y - 55

Then we add 55 on both sides of the equation.

53 = 4y - 55
+55       +55

108 = 4y

Finally we divide 4 on both sides.

108 = 4y
-----   -----
  4       4

27 = y is the answer
