Yesterday was the first day back and we got a new purple booklet. We also got new barn doors. We learned one step equations that were additive type and subtractive type. Mr. Harbeck mentioned that algebra is a balancing act. Whatever you do to one side, you have to do to the other side. For example, n+7=10.
HOW DO WE MAKE IT BALANCED?
First, you need to:
Isolate the variable
Cancel using the opposite
The rules still apply, but now you're subtracting. For example, y-13=-5.
