Answer:

D. 27

Step-by-step explanation:

If you plug in the variable and solve it is equal on both sides. EX.

1. 27/3 -3 = 27/9 +3

2. 9-3 = 3+3

3. 6 = 6

Answer:

X = 27

you multiply both sides and get 3x-27=x+27

then you move the terms and you get 3x-x=27+27 then calculate and get 2x=54 then divide and you get x==27
