n+7/6
If you want "the number" write 5 + 2X = 7 2X = 2 X = 1. So "five more than twice of one is 7.
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.
