Let N represent the 'number'. It looks like the first phrase would be expressed as 2(N + 5) which expands to 2N + 10, while the second expression would be 2N + 5, which is not the same.
Notice that the first one is 2 times the sum, while the second is 2 times a number.
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
X = 4(6-y)
twenty four times a number and add 19
Well, honey, if you're looking for the number that is three times a number and 16, you're looking for a math equation. So, let's break it down for you - the number you're searching for is 8. Yup, that's right, 3 times 8 is 24, and adding 16 gives you 40. Math can be a real trip, can't it?

" 3x + 5 " does.
Four times the number x.
It is 9*(n + 7)
It can be: 7x-11
X = 4(6-y)
