For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total cost of the meal is $32 and is represented by the equation 2x + 18 = 32. How much does each sandwich cost? A) $14
B) $22
C) $7
D) $28

C

Step-by-step 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.

answer: -2+√x,-2-√x
