Question 418714: A basketball team recently scored a total of 96 points on a combination of 2-point field goals, 3-point field goals, and 1-point foul shots. Although, the team made 54 baskets and 15 more 2-pointers than foul shots. How many shots of each kind were made?

You can put this solution on YOUR website!
Let a = number of 1-point shots made
Let b = number of 2-point shots made
Let c = number of 3-point shots made
given:
(1) 1%2Aa+%2B+2%2Ab+%2B+3%2Ac+=+96+
(2) a+%2B+b+%2B+c+=+54+
(3) +b+=+a+%2B+15+
----------------
This is 3 equations and 3 unknowns, so it's solvable
Multiply both sides of (2) by 3 and
subtract (1) from (2)
(2) 3a+%2B+3b+%2B+3c+=+162+
(1) -a+-+2b+-+3c+=+-96+
+2a+%2B+b+=+66+
Substitute from (3)
2a+%2B+a+%2B+15+=+66
3a+=+51
a+=+17
and
(3) +b+=+a+%2B+15+
b+=+17+%2B+15
b+=+32
and
(2) a+%2B+b+%2B+c+=+54+
17+%2B+32+%2B+c+=+54
+c+=+54+-+49+
c+=+5+
The number of 1-point shots made were 17
The number of 2-point shots made were 32
The number of 3-point shots made were 5
check:
(1) 1%2Aa+%2B+2%2Ab+%2B+3%2Ac+=+96+
(1) 17+%2B+64+%2B+15+=+96+
+96+=+96+
OK
