    37

    Step-by-step explanation:

    In the order of solving an equation you do the opposite of the original sign (-). so you add 9 on both sides of the equal sign and your left with w=37.

    The correct solution is 37. The student subtracted 9 from 28 instead of evening out the equation by adding 9 to 28, which resulted in the incorrect answer
