Write the following as an algebraic expression using x as the variable: The sum of a number and -8
4x
4n-5 (Which is four times a number minus 5)
Let the number be x and so the expression is 4x -3
The real answer is n-7
To write a verbal expression for (3x - 4), you can say "three times a number (x) minus four." This conveys the mathematical operations involved: multiplying the variable (x) by three and then subtracting four from the result.

To write twice the sum of a number and four, let the number be represented by the variable ( x ). The sum of the number and four can be expressed as ( x + 4 ). Therefore, twice this sum is written as ( 2(x + 4) ).
A numerical expression is an expression that uses number. For example, if a teacher told you to write four plus six subract two , you would simply write it in number form. 4+6-2.
The algebraic expression for 7 decreased by 4 times a number can be written as ( 7 - 4x ), where ( x ) represents the number. This expression captures the operation of subtracting four times the variable from seven.
