sum - means addition less - means subtraction twice - means multiply by 2

X = number. 4X + 9 = 2X - 15 ===========

2x - 4 = 6x -4 = 4x x = -1

Let the unknown number be x: x-4 = 2x -4 = 2x-x -4 = x So the number is -4

9+4x=2x-1 2x=-10 x=-5

There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)

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

Let the number be x Twice a number means 2x 7 less than twice a number means 2x-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.

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 ).

X = number. 4X + 9 = 2X - 15 ===========

This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6

2x - 4 = 6x -4 = 4x x = -1
