Question

Last season two running backs on the Steelers football team rushed or a combined total of 1550 yards. One rushed 9 times as many yards as the other. How many yards were rushed by each player?

Answer 1

First we define variables:
 x = distance traveled by player A
 y = distance traveled by player B
 We have the following system of equations:
 x + y = 1550
 x = 9y
 Solving the system we have:
 x = 1395
 y = 155
 Answer:
 x = 1395 yards (player A)
 y = 155 yards (player B)
