The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:


Car A

y = 45x + 20


Car B

y = 35x + 60

If you would like to find the amount of hours and the distance, you can calculate this using the following steps:

y = y
45x + 20 = 35x + 60
45x - 35x = 60 - 20
10x = 40
x = 40 / 10
x = 4 hours

y = 45x + 20 = 45 4 + 20 = 200 miles
y = 35x + 60 = 35 4 + 60 = 200 miles

The correct result would be 4 hours, 200 miles.

Answer:
