How many did Jenny have at first ?
~~~~~~~~~~~~~~~~

Let J be the number of stickers Jenny had at first; M be the number of stickers Melissa had at first. After Jenny had given Melissa 16 stickers, we have J - 16 = M + 16, or M = J - 32. Linda then gave 24 stickers to Jenny. Now Jenny has J - 16 + 24 = J + 8. Next, problem states that = , or = 5. To solve this equation, multiply both sides by (J-32) and simplify then. You will get J + 8 = 5*(J-32) J + 8 = 5J - 160 160 + 8 = 5J - J 168 = 4J J = 168/4 = 42. ANSWER. At first, Jenny had 42 stickers.

Solved.
