Can some one help pls

Hello !
Question : 3x + 18 = 54.
Solution.
3x=54-18
3x= 36
X = 36/3

Therefore x = 12

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
