Step-by-step explanation:
x = Gallons for city driving
24 - x = Gallons for highway driving
Miles drove before running out of gas = 421
Now let's solve for x, writing the following equation:
14x + 19 (24 - x) = 421
14x + 456 - 19x = 421
-5x = 421 - 456
-5x = - 35
x = -35/-5
x = 7 ⇒ 24 -x = 17
7 gallons were used for city driving and 17 gallons were used for highway driving
