Solving Linear equations Your Task is to demonstrate what you know about solving linear equations. You need to explain What is a linear equation? What does it mean to SOLVE an equation? What is GUESS AND CHECK and when should it be used? What is BACKTRACKING and when should it be used? What is INVERSE OPERATIONS ON BOTH SIDES and when should it be used? What is the DISTRIBUTIVE LAW and when should it be used? Finally provide evidence of your ability to solve linear equations from the most simple ( one step equations) to the most advanced ( with fractions, brackets and x’s on both sides) Information sources Presentation Formats Your teachers Your Text book Your Friends The Internet Powerpoint Word Paper based Three sites with good explanations and worked examples http://www.purplemath.com/modules/solvelin.htm This site provides a pretty clear explanation with examples. http://www.teacherschoice.com.au/Maths_Library/Algebra/Alg_21.htm Another site with explanations and examples. http://www.mathsnet.net/algebra/index.html This site has a lot of stuff about algebra.
