No, because numbers never vary. A variable expression must have something
in it that can take on different values, usually a letter, like 'x' for example.
A mathematical phrase is often referred to as an "expression." An expression can consist of numbers, variables, and operations but does not include an equality sign. Examples include (3x + 5) or (2a^2 - 4b). Unlike equations, expressions cannot be solved for a variable; they can only be simplified or evaluated for specific values.
A expression that only contains numbers is a Numerical
A numerical expression in math terms has numbers and operations like for an example 1. 4+9 2. (8-2)+5
There is, unfortunately, n equation in the question: only an expression. An expression cannot be solved for a variable.
A Numerical Expression is an expression only using numbers.
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
A variable expression includes variables.
You replace each variable by its value. Then you do the indicated calculations.

A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
No, you can only simplify an expression. To solve for a variable, it must be in an equation.

A numerical expression!
No, not all expressions contain variables. An expression is a mathematical phrase that combines numbers, variables, and mathematical operations. A variable is a symbol that represents a quantity that can vary, such as x or y. Some expressions may only contain numbers and mathematical operations, such as addition, subtraction, multiplication, and division. For example, "3 + 5" is an expression that only contains numbers and the addition operation. However, an expression that contains at least one variable is known as an algebraic expression, and this type of expression is commonly used in algebra to represent mathematical relationships between variables. For example, "2x + 4" is an algebraic expression that contains the variable x and represents a linear equation in which y is equal to two times x plus four.
