abs(2n - 7) = 3n/2 abs(2n - 7) may also be written as |2n - 7|
Twice the difference of a number and ten can be expressed as ( 2(x - 10) ), where ( x ) represents the number. This means you first find the difference between the number and ten, and then multiply that result by two. For example, if the number is 15, the expression would evaluate to ( 2(15 - 10) = 2 \times 5 = 10 ).
2n
If the number is represented by variable x, then twice the number is represented by 2x.

|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.
2x - 16 = 3x/18
If the number is represented by variable x, then twice the number is represented by 2x.
