Solve the equation: 13y − 5 = 9y + 27.

13y - 5 = 9y + 27 First we must collect all similar terms together on either side of the equation: 13y - 9y = 27 + 5. As you can see, if a term is moved to the other side of the equation, the opposite sign must be applied: 4y = 32. Now all the y's are collected together, we can follow the same approach as above in order get y on its own: y = 32/4 ...y = 8
