Answer:
the amount of matter is mass. how much space you take up
Step-by-step explanation:
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
The answer would be 18.8 gallons of gas needed
Hope this helps :)
