Question 1018688: Before the gates to the county fair opened one holiday morning, all 250 spaces in the north parking lot had filled. The number of cars was 20 less than twice the number of trucks. How many of each kind of vehicle were parked in the lot?

Make trucks = x
Cars = 2x - 20
Trucks + Cars = 250
x + 2x - 20 = 250
x + 2x = 250 + 20
3x = 270
x = 90
No. of trucks = 90
No. of cars = 160
Hope this helps :-)
