Explain the difference between an equation and an inequality. Describe both the set up and the solutions. Provide an example to justify your answer.
An equation includes an equal sign where both sides are equivalent whereas an inequality includes an inequality symbol where one side is not necessarily equal to the other side. In regards to the solution set, an equation has one and only one solution; an inequality has multiple options for solutions.
