    Conditional Equation
    An equation that is true for one or more values of the variable and false for all other values of the variable is a conditional equation.
    Contradiction
    An equation that is false for all values of the variable is called a contradiction. A contradiction has no solution.
    Identity
    An equation that is true for any value of the variable is called an identity. The solution of an identity is all real numbers.
    Solution of an Equation
    A solution of an equation is a value of a variable that makes a true statement when substituted into the equation.
