2x - 2y = 4 and

-y = 7 so

y = -7. That means

x = -5

-7 + -5 = -12

The gas tank in the car holds 20 gallons of gasoline. You used up 4 gallons and 1 quart on your trip. How much gasoline is left

erma4kov [3.2K]

There are 4 quarts in a gallon so the amount used can be shown as 4 1/4, or 4.25 so to find out how much gas is left in the tank you simply subtract 4.25 from 20.

20-4.25

=15.75

There is 15.75, or 15 3/4, gallons of gasoline left in the tank.
