A family room and two bedrooms cost $360 to steam clean the carpets. The amount of labor and the service fee incorporated into the total cost. Let x represent the labor costs per room and $45 equal the service fee. If it took the carpet cleaners (3) hours to complete the job, How much was the labor?

Choose the equation that represents this situation.
$360 - 45= 3x
$360 + 3x = $45
$45 + 3x = $360
$360 + $45 = 3x
