Dependable Maids, a housecleaning service, charges $20 for a service call (just to come to the house) plus $15 per hour to do the cleaning job. Clean as a Whistle, another housecleaning service, charges $35 for a service call plus $12 per hour to do the cleaning job. How many hours would a job have to take for the bills of both cleaning services to be the same?​

here ya go :>

Step-by-step explanation:

2x+5=−7(x−2)

Step 1: Simplify both sides of the equation.

2x+5=−7(x−2)

2x+5=(−7)(x)+(−7)(−2)(Distribute)

2x+5=−7x+14

Step 2: Add 7x to both sides.

2x+5+7x=−7x+14+7x

9x+5=14

Step 3: Subtract 5 from both sides.

9x+5−5=14−5

9x=9

Step 4: Divide both sides by 9.

9x

9

=

9

9

x=1

hope it helps
