Step-by-step explanation:

Step 1: Subtract 3x from both sides.

7x− 7− 3x = 3x−23− 3x

4x−7=−23

4x−7+7=−23+7

4x=−16

Step 3: Divide both sides by 4.

4x

4

She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.
