s= -8 + n, or s=n - 8, where s is the sum and n is the number
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
The sum of fifteen times a number and eight.

The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
Let the number be x and so the expression is 8x
x+(-8)This simplifies to x-8
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
The sum of fifteen times a number and eight.
Watch closely:The sum of 'n' and '8' is written as (n + 8).
4*(x - 8)
x/8
