To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.

If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
The number is 17.
