Lesson Summary:

In this lesson, the instructor demonstrates solving linear equations using the addition property of equality. The examples cover situations where neither side of the equation is simplified, and the instructor shows the process of simplifying each side before adding or subtracting terms. The lesson includes examples where the left side of the equation requires the use of the distributive property, and where there are variables on both sides of the equation. The importance of checking answers is emphasized, and students are encouraged to practice and approach problems in a way that works best for them.

    This lesson takes on some more complicated equations. There are more terms on each side of these equations, and simplifying is necessary before solving. Again, all steps are explained very well.
