Answered by Reiny
number of coins for Jim --- x
number of coins for Holly --- 4x/3

(1/2)(4x/3) = (1/3)x + 10
2x/3 = x/3 + 10
times 3
2x = x + 30
x = 30

Jim has 30 and Holly has 40

check:
does Holly have 1/3 more than Jim ? YES
what is 1/2 of Hollys ? 20
what is 1/3 of Jims ? 10
is 1/2 of Holly's 10 more than 1/3 of Jim's ? YES
