The answer could be any number between 39 to 45.
When doubled this produces 78 to 90. and with 7 subtracted this gives 71 to 83.

The answer 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.
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).

It's seven
The answer is 11 !
x / (2y - 7)
5+5=1010-7=3the answer is 3
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
Example:VERBAL SENTENCE:Seven more than twice a number is four less than thrice the number.MATHEMATICAL EQUATION:(seven more than) (four less than)(twice a number) is (thrice a number)2x + 7 = 3x - 4=Earljoyce8♥=Hope this helps!!
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.
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
