- 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.
