1. 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 ≤.

2. 3-2 Solving Inequalities Using Addition or Subtraction
What is the Subtraction 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 ≤.
