Question

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

Answer 1

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

since m = w-18,

2(w-18-9) = w+9
2w-54 = w+9
w = 63
