<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>
Answer:
See Explanation
Step-by-step explanation:
Given

A linear equation is represented as:

Where
and

c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5




<em>60 miles traveled</em>
Solving (b): s = 36


Collect like terms


Solve for r

<em>42 gallons used</em>
The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.
-2.7=y then make that equal sign into the normal sign again. -2.7
