Melissa made a total of 14 baskets during her last basketball game. she made a number of 2-point baskets and a number of 3-point baskets for a total of 33 points. using matrices to solve, how many 3-point baskets did melissa make in her last basketball game?

Melissa made 5 3-point baskets in her last basketball game. 

This problem is solved using a system of equations which can be set up as follows: 

x + y = 14
2x + 3y = 33

First, you have to isolate x. So x = 14 - y. You would then take that equation and plug it into the x for the second equation. 

[ 2 (14 - y) + 3y = 33 ]

Last, isolate y. After solving for y, the answer is 5. 

28 - 2y + 3y = 33

28 + 1y =  33

1y = 5

y = 5
