Answer:
y=3
Step-by-step explanation:
3 (3y - 9) = 0
Divide each side by 3
3/3 (3y - 9) = 0/3
3y -9 = 0
Add 9 to each side
3y -9+9 = 0+9
3y =9
Divide by 3
3y/3 = 9/3
y =3

Given:
A car starts with a dull tank of gas
1/7 of the gas has been used around the city.
With the rest of the gas in the car, the car can travel to and from Ottawa three times.
Question asked:

The car can complete 1 trip by using =
=
=
= tank of gas
Thus, tank of gas used for each complete trip to Ottawa.
The answer would be 16
11 + (8-3)^2 - 20 = 16
