Solve the Variable.

n/3-3=12

N/3 - 3 = 12

*add 3 to both sides

n/3 - 3 + 3 = 12 + 3

n/3= 15

*multiply 3 to both sides

n/3 * 3 = 15 * 3

n = 45

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.
