Pee's bag contains 7 times as many coins as Poo's bag. If Pee gives 12 coins to Poo, the two boys will have the same number of coins. What is the total number of coins?
e = 7 o This is given
e-12 = o + 12 sub in the red equation
7 o - 12 = o + 12
6 o = 24
o = 4 then pee = 7 * poo = 28 total = 32 coins
