The answer is 11 !

Let the number be x and so if 2x -7 = 15 then the value of x is 11

This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6

If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
