a basketball player scored 17 timea during one game. He scored a total of 28 pts,two for each twopt shot and one for each free throw. How many twopt shots did he make? How many free throws?
How many twopt shots did he make? simplify

let x = 2pt shots and y = free throws
x + y = 17, therefore x = 17y
2x + y = 28
Substitute 17y 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.
