The best way to find it is to use the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com.  At the bottom of the page there is a single link that takes you to my Homepage.  On my Homepage, look for the link \"Basic, Intermediate, and College Algebra: One Step at a Time.\"  Choose \"Basic Algebra\", and look in \"Chapter 4\" for \"Section 4.07 Solving Systems of Equations.\"  Here you will find my own non-traditional explanation that my own students used to find much easier to understand than most of the other textbooks being used.  I also have lots of examples, exercises, and answers.  In addition, most of the hardest problems are solved in color on the MATH IN LIVING COLOR pages that go with this topic.  It's ALL FREE on my website!!!\r<BR>\n" );
