Answer:
Gas left after 5 hours is: 10 gallons
Gas left after t hours is : sorry I don't know
Step-by-step explanation:
Subtract 2 everytime you count an hour
Hope this helps
-6x + 8y = 6 . . . (1)
-12x + 16y = 8 . . .(2)
(1) x 2 => -12x + 16y = 12 . . . (3)
(2) - (3) => 0 = -4
Therefore, the system has no solution.
