If Will gives Molly $9 he will have the same amount as her. If Molly gives will $9 the ratio of the money she has to the money Will has will be 1:2. How much money does Will have in the beginning

(w-9) = (m+9)
(m-9)/(w+9) = 1/2

w - m = 18
-w + 2m = 27

m = 45
w = 63

so, we start out will=63, molly=45

63-9 = 54 = 45+9
45-9 = 36 = 1/2 (63+9)
