In simple words, a variable is a quantity that can be changed and is not fixed. Variables are essential as they form a major algebra component. We usually use “ x ” and “ y ” to express an unknown integer. However, it isn’t necessary, and we can use any letter. Let us take an example of the algebraic expression 2x + 6.
