Answer:
B. r + l = 45; 2r + 3l = 96
39 regular; 6 long-distance
Step-by-step explanation:
There were 45 baskets, so
(1) r + l = 45
There were 96 points in the game, so
(2) 2r + 3l = 96
Solve equation (1) for l
                     l = 45 – r     Substitute the value for l in Equation (2)
2r + 3(45 – r) = 96      Remove parentheses
  2r + 135 - 3r = 96      Combine like terms
          -r + 135 = 96      Subtract 135 from each side
                   -r = -39      Multiply each side by -1
                    r = 39       Substitute the value of r in Equation (1)
            39 + l = 45        Subtract 39 from each side
                    l = 6
===============
Check:
(1) 39 + 6 = 45
          45 = 45
(2) 2×39 + 3×6 = 96
            78 + 18 = 96
                    96 = 96
