So, this is simple, but needed to be one step at a time. We need to find out how much she earns by washing one window, and to do that we need to divide $81 by 9, and after that division she earns $9 per window. If she washes 5 windows, multiply $9 by 5 as that's how much she's going to earn. So, when she washes 5 windows, she earns $45.

PLZZZZZZZZZZZZZZZZZZZZZZZZZ HELP!!!
NISA [10]

Answer:

Step-by-step explanation:

Instead of dividing both sides by 5, it is multiplied

5x + 3 = 6            {Subtract 3 from both sides}

5x + 3 - 3 = 6-3

            5x = 3       {Divide both sides by 5}

           5x/5 = 3/5

                 x = 3/5
