Question

A basketball player scored 22 times during one game. HeHe scored a total of 29 points, two for each two-point shot and one for each free throw. How many two-point shots did hehe make? How many free throws?

 

Answer 1

Let x = the number of two-point shots

 2x + y = 29

-(x + y = 22) 

x = 7

7 + y = 22

y = 15
