In this lesson, we learn how to solve rational equations and avoid undefined fractions. By multiplying both sides by the least common denominator or through the jealousy method, we can get an equivalent fraction on both sides of the equation. We then simplify the equation and solve for the variable, checking our answers to ensure we haven't created any undefined fractions. This problem requires us to incorporate a lot of algebraic ideas and is a great exercise in problem-solving.
