Students have complained that their teacher is making up the rules for solving equations just to annoy them. "Where is it in my text?" Often the rules were given years ago, and the student is assumed to have internalized them. Here are the rules as they appear in those earlier years. The answers are fully laid out to show the student HOW to answer. The lessons on how to read and summarize word problems are given in different ways because the student in Grade 5 is just learning to write compound sentences, and the student in Grade 7 is just learning to write complex sentences.
