Answer:
B. Collect like terms
Step-by-step explanation:
The first step is to subtract
from each side of the equation, and we have the following

We can see that on the left side of the equation we have <u>like terms</u> (the two terms containing x)
so the next step is to combine or collect those like terms
and
to simplify the expression:

We are not distributing or eliminating the
(because there is still a term with x on the right side), nor are we completely isolating the
yet.
What was done in this step was to collect like terms.
