Selection Reflection

So.. this is a personal blog post to myself. To look back and reflect on linear systems of equations while studying for the exam!!!
First thing we learnt was THE SUBSTITUTION METHOD.
It wasn't to bad just need to go through the steps into finding out the equation. Remember to plug the answer back into the equation to find out if its right.
Second thing we learnt was LINEAR COMBINATION ( ADDITION SUBTRACTION METHOD).
Just need to remember to line them up and when to add and when to subtract.
Third thing we learnt was SYSTEM TYPES NAMES.
Consistent system( one unique ordered pair solution).
Inconsistent system(no solution).
Dependant system(infinitely many solutions, in ordered pair).

Forth thing we learnt and the final thing we learnt was WORD PROBLEMS. AHHHH! OK i did not get this! I think my problem was that I just didn't know the steps to each problems. Once i get and understand the steps i can work through it. There are example problems on the coursework drive they did help. RULES:

1. Define two variables( linked some how).
2. Create two equations using two Variables.

So.. that was all the different things we learnt in this unit. I understand it for the most part beside WORD PROBLEMS. Before the exam I really need to get a good understanding on how word problems really work and each steps.
