3-2 Solving Inequalities Using Addition or Subtraction What are Equivalent Inequalities? Inequalities that have the same solutions. What is the Addition Property of Inequality? Let a, b, and c be real numbers If a > b, then a + c > b + c If a < b, then a + c < b + c This property is also true for  and ≤.
