Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.

You can die after 24 hours, be careful and try not to be sick more than twice. Hold it in, just please.
Yes, because it is divisible by more than two factors. For ex. 24 : 1,2,3,4,6,8,12 an 24.
Suppose the number is n Then 2n = n/2 + 12 Multiply through by 2: 4n = n + 24 Subtract n from both sides: 3n = 24 Divide both sides by 3: n = 8
