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)

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. Work on section C solving simple equations
Two versions of an Interactive that helps you understand operations on both sides
 http://nlvm.usu.edu/en/nav/frames_asid_201_g_4_t_2.html?open=instructions&from=
category_g_4_t_2.html
Equation balance simple version (no negatives)

http://nlvm.usu.edu/en/nav/frames_asid_324_g_4_t_2.html?open=instructions&from=
category_g_4_t_2.html
Equation balance with negatives
Two sites that has worked examples at progressive levels of difficulty
 http://www.sosmath.com/algebra/solve/solve0/solve0.html
This site has a series of worked examples that get progressively harder it covers the
complete level of difficulty
 http://education.yahoo.com/homework_help/math_help/problem_list?id=minialg1gt_1
_1
This site has lots of examples with a step by step “Tutor” to show how to solve them
Two sites to practice solving equations and check your answers
 http://www.bbc.co.uk/education/mathsfile/shockwave/games/equationmatch.html
BBC site with problems and matching game with 3 levels
 http://www.thatquiz.org/tq/practice.html?algebra
Select solve for x up to level 4 to practice and self correct linear equations at year 8 level
