14+ 13y - 13y = 20y - 13y -21 (taking away the smallest y value from both sides)
14 = 7y - 21
14 + 21 = 7y - 21 +21 (+21 on both sides to remove -21 if we do -14 then we will have nothing on other side)
35 = 7y
35/7 = 7y/7 (dividing 7 on both sides)
5 = y
answer is 100% correct no doubts. hope it helped you.
