Find how many kilometers they traveled by

bike.
Enter the correct answer.
George and Carmen went on a bicycle
trip. They took a bus to their starting
point, and then biked the rest. They
traveled 200 kilometers in total, and
they biked 40 kilometers more than they
were bussed.
Let x = kilometers traveled by bike and
y = kilometers traveled by bus.

1y+40x=200
Original equation
40x+1y=200
-40x -40x=
y=200-40x
Substitue y equivalent
1(200-40x)+40x=200
200 - 40x +40x=200
Cancel out 40x (-+ equal positive = 0)
200=200 km travelled by bike
