They are used to represent known and unknown values in equations. Usually x, y, and z are unknown; and a, b, and c are known. But u can use anything to represent anything! It helps to solve for unknowns that you need to figure out!

A letter or symbol used to represent an unknown quantity is typically called a variable. In mathematics, common variables include letters such as ( x ), ( y ), and ( z ). These variables can stand for different values in equations and expressions, allowing for the representation of general cases and relationships between quantities.
In mathematics, an unknown quantity represented by a letter is usually called a variable. Variables are used to symbolize values that can vary in an equation or formula. They allow us to write general expressions that can represent multiple possible scenarios.
x or any other variable
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
Nothing specifically is "done" to the variable; variables are generally used to represent either:* A quantity that is initially unknown (and should be solved for), or * A quantity that can be anything - to analyze what happens no matter what a certain value is.
In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
In math, the letter "n" is commonly used as a variable to represent a number that is not specified. It is often used in equations and formulas to indicate a variable quantity that can take on different values.
