Answer: The number is 12

Step-by-step explanation:

Let x= the number that is unknown

The sum of three and a "number"= 3+"x"

Divided by three, means that x+3 is divided by 3

Is five, means that (x+3)/3=5

Algebra:


(x+3)/(3)=5

Multiply by 3 to arrive at x+3=15

Subtract both sides by 3, then x=12
