Answer:
B, C
Step-by-step explanation:
7 - x = 18
A.
7 - 2x = 18 - x
126 - 14x = 324 - 18x
We are nowhere near the solution.
B.
-x = 11
x = -11
This works.
C.
7 = x + 18
-11 = x
This works.
D.
25 - x = 36
-25 + x = -36
This does not help.
E.
7 = x + 18
0 = x + 11
We still do not have a solution.

Step-by-step explanation:i need the think points
The unit rate will be "23.5 miles/gallon". In the below segment, a further solution to the given question is provided.
Given values in the question are:
Total distance,
= 188 miles
Total gas used,
= 8
Now,
⇒ The rate of gas consumption will be:
= 
By putting the given values in the above formula, we get
= 
= 
Thus the above is the appropriate solution.
