5+5=10
10-7=3
the answer is 3
blah
twice a number can be 2x and six less than it is 2x-6.
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
Given a number N, you would have: 2*N - 5
Let the number be x and so the expression is: 2x-2
blah
The answer is 11 !
It's seven
twice a number can be 2x and six less than it is 2x-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!!
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
Let the number be x and so if 2x -7 = 15 then the value of x is 11
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).
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
