Lesson Summary:
In this Pre-Algebra lesson, the properties of equality are used to solve equations. The lesson covers how to add or subtract the same number from both sides of the equation and how to multiply or divide both sides by the same number. The transcript includes examples of solving basic equations and more complicated ones involving combining like terms. The lesson emphasizes the importance of getting the variable by itself to find its value.
Lesson Description:

Staff Review
This video continues where part 1 leaves off. You will learn how to multiply or divide both sides of the equal sign of a basic equation using properties of equality in order to get the variable by itself. This time, you need to use what was learned in part 1 and add a new technique. -

I learned multiply or divide both sides of the equal sign of basic equality in order to get variable by itself.
