Answer:

b = 5

Step-by-step explanation:

Whatever you do to one side, you must do to the other side in order to make the equation stay true.

1. Subtract 22 from both sides.

-3b + 22 - 22 = 7 - 22

-3b = -15

2. Divide both sides by -3.

-3b/-3 = -15/-3

b = 5

^ That's the final answer!

The answer would be -3×5+22
