Answer:

  • 144 free throws
  • 177 2-point field goals
  • 121 3-point field goals

Explanation:

Let a, b, c represent the number of 1-point, 2-point, and 3-point goals, respectively.

a +2b +3c = 861 . . . . . . total number of points

b = 2c -65

a = b -33

Substituting for a, then b, we have ...

(b -33) +2b +3c = 861

3b +3c = 894 . . . . . . . . . . add 33, collect terms

b +c = 298 . . . . . . . . . . . . divide by 3

(2c -65) +c = 298 . . . . . . substitute for b

3c = 363 . . . . . . . . . . . . . add 65

c = 121 . . . . . . . . . . . . . . . divide by 3

b = 2(121) -65 = 177

a = 177 -33 = 144
