3x = 27 What should be done to each side of the above equation to isolate x?
A. add 3 to each side of the equation
B. subtract 3 from each side of the equation
C. multiply each side of the equation by 3
D. divide each side of the equation by 3

D

Step-by-step explanation:

Since you are trying to make x on its own, you are trying to get rid of the co-efficient. The co-efficient is three, so you divide 3 by 3, which would equal one, leaving x on its own. Whatever you do to one side you do to the other, so you would divide 27 by 3 as well.

x = 9
