The ratio of A's stickers to B's stickers was 3:4.

After A bought another 18 stickers and B lost 10 stickers, the ratio became 3:2. Find the number of stickers both of them had at first.

a/b = 3/4

(a+18)/(b-10) = 3/2

4a = 3b

2(a+18) = 3(b-10)

2a+36 = 4a - 30

2a = 66

a = 33

b = 44

check:

33/44 = 3/4

(33+18)/(44-10) = 51/34 = 3/2
