In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation or an algebraic expression. 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.

Algebra 1 or elementary algebra deals with solving the algebraic expressions for a viable answer. In algebra 1, simple variables like x, y, are represented in the form of an equation. Based on the degree of the variable the equations can be categorized into different types, namely linear equations, quadratic equations, cubic equations, and so on.
