Unit 2: Equations
How Do We Solve One Step Equations?
In this unit, I am going to obstacles around x and ask you to cancel out these obstacles.
How many can you cancel? Are you brave enough to accept my challenge?

I said, Are you brave enough to accept my challenge?
We cancel operations around the variable (x) by using inverse operations.
The inverse operation of addition is subtraction and vice versa.
The inverse operation of multiplication is division and vice versa.
When you cancel out addition and subtraction, you get the term plus zero.
This is the definition of the Identity Property of Addition that we discussed in the last lesson.
When you cancel out multiplication and division, you get the term times one.
This is the definition of the Identity Property of Multiplication, also in the last lesson.
