Two is a number.
Twice is an operator which means multiply by 2.
Several is a non-specific number, more than 2 but not very many.
Two refers to the quantity of 2. Example: I have two apples. Twice means "two times" which refers to both multiplication and two occurrences. For example: I have twice (two times) the amount of clothes than my sister. OR I went to the mall twice (two times) today.

The difference between a number x and twice y is equal to fifteen.
It does not mean anything at all. "Twice a number" is only one number while "the difference" must refer to two numbers, not just one.
18 and 6
The expression "twice the difference of x and 5" would look like this: 2(x-5). To solve the problem, you would first subtract 5 from x, and then multiply the difference by two.
2*abs(2-n) = 9
twice the difference of three times a number and eight
Bi-monthly has an ambiguity to it, it can mean 'twice a month' or 'every two months'. Where as semi-monthly means only 'twice a month'.
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.
If the higher is 3 times the lower, the difference must be twice the lower so the numbers are 8 and 24.
