For additional help, explanation, examples, exercises, and answers, please go to my website, by doing a "Bing" Search for my last name "Rapalje". Look for "Rapalje Homepage" near the top of the search list. Then, near the top of my Homepage, look for "Basic, Intermediate and College Algebra: One Step at a Time," select "Basic Algebra" and in "Chapter 1", look for "Section 1.11 Inequalities". This is my own non-traditional explanation that my own students have found MUCH easier to understand than the traditional textbooks. In addition to my explanations, examples and exercises, I have my "MATH IN LIVING COLOR" pages where I solved many of these exercises IN COLOR!!
