Identity Equation

An identity equation is a mathematical equation that is universally true for any substituted value of the variable. Because the algebraic expressions on both sides are equivalent, systematically solving the equation entirely eliminates the variable and leaves a perpetually true constant statement, such as 14=1414=14. Consequently, the solution set for an identity equation encompasses all real numbers.
