abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
2n
If the number is represented by variable x, then twice the number is represented by 2x.
It can be: 2x-25 or 25-2x or maybe the absolute value of (2x-25).

|5n - 2n|
The difference between a number x and twice y is equal to fifteen.
abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
2 x = 8 + 4x
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
2n
twice the difference of three times a number and eight
Twice a number can be represented as 2x, where x is the unknown number. Adding 27 to this expression gives 2x + 27. Therefore, "twice a number plus 27" can be written as the algebraic expression 2x + 27.
If the number is represented by variable x, then twice the number is represented by 2x.
2x - 16 = 3x/18
