In this lesson, the teacher demonstrates how to solve rational equations containing fractions. To solve these equations, one can multiply all terms by the least common denominator, make all denominators the same, or combine two terms with the same denominator. The teacher also emphasizes the importance of checking solutions, especially in rational equations, because if replacing the variable with a solution makes one or more denominators equal to 0, it is not a solution.
