Lesson Summary:

In this lesson, students are introduced to the addition and multiplication properties of equality, which are important for solving equations. The addition property allows numbers to be added to both sides of the equation, while the multiplication property allows numbers to be multiplied to both sides. The lesson walks through several examples of using these properties to solve equations, in both horizontal and vertical formats. Different ways of solving equations are addressed, with a focus on finding the one answer to the problem.

Lesson Description:

Properties of equality are explained in order to solve equations.

This video explains how to solve basic pre-algebra equations by using properties of equality. Add or subtract the same number from both sides of the equal sign to get the variable all by itself. Very good explanations and various techniques are used in this video.
