asked 01/10/19The physical education instructor asked each student to do a total of 36 pull-ups and push-ups in 3 minutes. The instructor wanted students to do 8 times as many push-ups as pull-ups. Write a system of linear equations that represents this situation. How many pull-ups and push-ups were required in 3 minutes?
