-2x - 18 = 611-2x) + 4x
Serhud [2]

Answer:

x = (-629)/4

Step-by-step explanation:

Solve for x:

-2 x - 18 = 4 x - 2 x + 611

4 x - 2 x = 2 x:

-2 x - 18 = 2 x + 611

Subtract 2 x from both sides:

(-2 x - 2 x) - 18 = (2 x - 2 x) + 611

-2 x - 2 x = -4 x:

-4 x - 18 = (2 x - 2 x) + 611

2 x - 2 x = 0:

-4 x - 18 = 611

Add 18 to both sides:

(18 - 18) - 4 x = 18 + 611

18 - 18 = 0:

-4 x = 611 + 18

611 + 18 = 629:

-4 x = 629

Divide both sides of -4 x = 629 by -4:

(-4 x)/(-4) = 629/(-4)

(-4)/(-4) = 1:

x = 629/(-4)

Multiply numerator and denominator of 629/(-4) by -1:

Answer: x = (-629)/4

AlexFokin [52]

Based on the fact that Tim forgot to refuel the vehicle and the amount per gallon at the rental place, Tim will have to pay an extra amount of d. <u>$57.88.</u>

<h3>How much will Tim pay?</h3>

According to the conditions, Tim will have to pay for the complete refueling of the car should he forget to refuel. He will also have to pay a $5.00 refueling fee.

The car is almost empty which means he will also pay for the entire capacity of the car.

The amount Tim will pay is:

= (Cost per gallon x Total fuel capacity) + Refueling fee

= (4.50 x 11.75) + 5

= $57.88

In conclusion, option D is correct.
