<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
