hope this helps=


your formula is:
bx + a(m-x) = abm/c
a = miles per gallon of the first car.
b = miles per gallon of the second car.
c = combined mileage of both cars.
m = total miles traveled by both cars.
x = total miles traveled by first car.
m-x = total miles traveled by second car.
number of combined gallons consumed is equal to m/c
number of gallons consumed by first car is x/a
number of gallons consumed by second car is (m-x)/b
