n + 10
(6+n) n= a number
the sum of a number and three
It is n + 14.
Assuming the number is x, then: x + 9
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
The algebraic expression is n + 100, where n is the unknown number.
