Oh, isn't that a happy little math problem? To find the number, we simply need to set up an equation. Let's call the number "x." So, 2x - 7 = 15. By adding 7 to both sides and then dividing by 2, we find that the number is 11.
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).
20
blah
It's seven
The answer is 11 !
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
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 'z', then five less than twice the number is ( 2z - 5 ).
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
