For each pair of equations, determine whether the second equation is the result of a valid operation on the first. If so, what is the operation? If not, why not?
10
30 and 10 = 30(x – 3)

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.
