16) A basketball player scored 32 points in a game. The number of three-point field goals the player made was less than three times the number of free throws (each worth 1 point). Twice the number of two-point field goals the player made was 6 more than the number of three-point field goals made. Find the number of free-throws, two-point field goals, and three-point field goals that the player made in the game. Solve the system of equations using matrices....
