Section 5.1: Systems of Linear Equations in Two Variables (page 482)

Systems: Equations: Two Variables

A pretty good collection of examples which illustrate both the substitution and elimination method are provided in the Exercises for this section.

Minimal List of Exercises Page 492.

If you understand the previous material you should be able to answer the following questions.
Each of these questions should be answered. Most of these questions are included in the MyMathLab homework requirement. If a particular concept is difficult for you, you should study the related text material and then try to answer some additional questions from the list provided by the department. In each case you are expected to make an honest adult evaluation of your understanding of the concept. Your ability to answer these questions is one tool to help you make that evaluation.

Section 5.1 Exercise Set: 1, 3, 5, 7, 9, 11, 17, 19, 21, 25, 27.

Section 5.2: Systems of Linear Equations in Three Variables (page 498)

Elementary Row Operations Calculator

A collection of examples which illustrate the use of elementary row operations are provided in the Exercises for this section.
