Answer:
B. Collect like terms
Step-by-step explanation:
The first step is to subtract [tex]20x[/tex] from each side of the equation, and we have the following
[tex]20x + 5y -20x=40-20x[/tex]
We can see that on the left side of the equation we have like terms (the two terms containing x)
so the next step is to combine or collect those like terms [tex]20x[/tex] and [tex]-20x[/tex] to simplify the expression:
[tex](20x-20x)+5y=40-20x\\5y=40-20x[/tex]
We are not distributing or eliminating the [tex]x[/tex] (because there is still a term with x on the right side), nor are we completely isolating the [tex]y[/tex] yet.
What was done in this step was to collect like terms.
