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.
