Answer:

C

Explanation:

thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.

First, subtract 18 from both sides to eliminate it.

2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14

Next, separate the 2 from the x by dividing it from both sides:

2x = 14 ----> 2x/2 = 14/2 ----> x = 7

By solving this equation, we find that x, or one sandwich, costs $7.
