A certain number was divided my 3; 3 was added to to the result. the final answer is 8. what is the number?

The number is 15.

Step-by-step explanation: We are given a certain number we don't know about. Since it's value is unknown it is a variable. We'll call this variable "x". That number, x, is divided by 3, and then 3 was added to x to make 8. So then if x =  15, then dividing it by 3 would make 5, and adding 3 to that would make 8.

Another way to solve this, or check your work, is to work the problem out in reverse. Starting with the number 8, subtract 3 and then multiply that number by 3. This will give you the number 15. Which shows that the answer is correct.
