a basketball player scored 17 timea during one game. He scored a total of 28 pts,two for each two-pt shot and one for each free throw. How many two-pt shots did he make? How many free throws?
How many two-pt shots did he make? simplify
let x = 2-pt shots and y = free throws
x + y = 17, therefore x = 17-y
2x + y = 28
Substitute 17-y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
