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)
