3*(n - 5) = 2*n + 11
13 < 2n - 5 < 21
2n - 2
2x-3
2k - 7
3a-6x2
32 - 2x < 18
twice a number can be 2x and six less than it is 2x-6.
6x -5 < 2x +10
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
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.
3*(n - 5) = 2*n + 11
13 < 2n - 5 < 21
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 ).
