Hi,
9 more 2-pointers than foul shots, 46 baskets in all
Let x and (x+9) represent the number of foul shots and 2-pointers respectively
then 3 pointers would be [46 - x - (x+9))] 0R (37-2x)
Question States***total of 81 points
1*x + 2*(x+9) + 3*(37-2x) = 81
Solving for x
1x + 2x+ 18 + 111 -6x = 81
129 - 3x = 81
48 = 3x
16 = x, the number of foul shots.
25 2-pointers, (16+9)
5 3-pointers (46 - 16 - 25)

50 + 15 + 16 = 81 points total
