Let the number be x 12-2x = -7 -2x = -7-12 -2x = -19 x = 9.5

2n - 20 = 50

As an algebraic expression it is: 2x-9

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.

2x - 7 = -1

The number is 7.

If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6

x / (2y - 7)

2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4

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