Step-by-step explanation:
47-15=32
32
47-
15
L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles
