Answer:

Your answer should be b.) He subtracted 4 instead of dividing 4 on both sides.

Step-by-step explanation:

When trying to find the value of x, you need to divide on both sides instead of subtracting, so after the first step, he would have needed to divide 4x/4 and 20/4 to get the actual answer of x=5.
