For additional help on this very important topic of EQUATION SOLVING see my own website. You can do a "Bing" or "Google" search for my last name "Rapalje". Look for "Rapalje Homepage" near the top of the search list. On my Homepage, click on "Basic, Intermediate and College Algebra: One Step at a Time," and look in "Chapter 1" for "Section 1.08 Equation Solving." According to my own students, this section is a LOT easier to understand than the traditional textbooks. See also the "Math in Living Color" section in which many of these exercises are solved IN COLOR!
