Systems of Equations: Substitution, Simultaneous, Cramer's Rule: Algebra Practice Workbook with Answers (Improve Your Math Fluency)
<b>CONTENTS</b>: This is an <b>intermediate</b> algebra workbook devoted to solving systems of equations. (This book isn't for algebra beginners.) This workbook helps to develop fluency with the following algebra skills:<ul><li>solving two equations with two unknowns (x and y)</li><li>solving three equations with three unknowns (x, y, and z) </li><li>the method of substitution</li><li>simultaneous equations (setting up equal and opposite coefficients)</li><li>2x2 and 3x3 determinants</li><li>Cramer's rule for systems of equations</li></ul><b>AUTHOR</b>: Chris McMullen earned his Ph.D. in physics from Oklahoma State University and currently teaches physics at Northwestern State University of Louisiana. He developed the <i>Improve Your Math Fluency</i> series of workbooks to help students become more fluent in basic math skills.<br /><br /><b>EXAMPLES</b>: Each section begins with a concise description of the main concepts, an outline of the strategy, and an example with explanations. The examples should serve as a useful guide until students are able to solve the problems independently.<br /><br /><b>ANSWERS</b>: Answers to 100% of the exercises are tabulated at the back of the book. This helps students develop confidence and ensures that students practice correct techniques, rather than practice making mistakes.<br /><br /><b>PRACTICE</b>: With no pictures, this workbook is geared strictly toward learning the material and developing fluency through practice.<br /><br /><b>PHOTOCOPIES</b>: The copyright notice permits parents/teachers who purchase one copy or borrow one copy from a library to make photocopies for their own children/students only. This is very convenient if you have multiple children/students or if a child/student needs additional practice.<br /><br /><b>EDITIONS</b>: Available in both print and e-book editions. The print edition ISBN is 1941691048.
