3x+2.
x equals any given number.
The expression "3x" can be described in words as "three times a variable x." It represents the product of the number three and the variable x, indicating that x is multiplied by three.
The variable expression for "6 times a number p" is written as ( 6p ). This expression represents the product of the constant 6 and the variable ( p ). It can be used to calculate the value when ( p ) is known.

A number in front of a variable is called a coefficient. It represents how many times the variable is multiplied. For example, in the expression (3x), the number 3 is the coefficient of the variable (x). Coefficients can be positive, negative, or zero, and they play a crucial role in determining the value of the expression when the variable is assigned a specific number.
The expression can be thus: 3x-3 whereas x is the unknown variable

The expression -2 3x can be represented as "negative two times three times a variable x" or "negative two multiplied by three times x." The expression 3x - 2 can be phrased as "three times a variable x minus two." Both expressions involve multiplication and subtraction of the variable x with constants.
An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.
