Lesson Summary:

In this lesson, the instructor goes over how to solve rational equations by clearing through the denominators and eliminating fractions to make the problem easier to solve. They caution viewers to be careful when simplifying as opposed to solving, as the two require different methods. The instructor gives several examples and walks through each step, making sure to check the solution and emphasize the importance of not dividing by 0. This lesson is great for anyone who needs a refresher on solving rational equations.

Lesson Description:

Part 5 of Solving Rational Equations; more examples, shows the difference between simplifying and solving.
