ScribePost For January 5th.

Tuesday, January 6, 2009
On Monday, we made a new booklet for our algebra unit. We learned one step equations that were Additive and Subtractive type. One way to solve these equations is to "balance" it. What ever you do to one side, you have to do to the other side. Example : n+7 = 10


N+7= 10








But how can we balance it?


You have to..

Isolate the variable
Cancel using the opposite
Balance
Verify








Subtractive Type
The rules are pretty much the exact same thing and the only thing different is that your subtracting. Example : y-13=-5
