A basketball player scored 12 times during one game. He scored a total of 22 points, two for each field goal and one for each free throw. How many field goals did he make? How many free throws?

ohhh mehn that requires your brain
This requires setting up 2 equations with 2 variables. Let's say fg is the number of field goals made and ft is the number of free throws made.

Since we know a field goal is 2 points and a free throw is 1 point, we know that:

2fg + 1ft = 22

Since we know he scored 12 times, we know that:

fg + ft = 12

Now you can just subtract the second equation from the first. This would leave you with:

fg = 10

So, he scored 10 field goals. Using our equations, that must mean that he scored 2 free throws.
