Mrs Murphy absent....see a friend for the notes you more detailed notes you missed.
BASIC IDEA:
solving equations for x
what you do to one side of the equation you must do the the other
do the opposite of what is happening to x
ex. x+3 =10 you subtract 3 from both sides
4x=20 you divide both sides by 4
