How to solve a one step equation by multiplying by the reciprocal

The video tutorial explains two methods for solving equations involving fractions. The first method involves eliminating fractions by using the least common denominator (LCD), which simplifies the equation. The second method uses the reciprocal to solve the equation more directly. The tutorial emphasizes the importance of understanding fractions and the benefits of eliminating them for solving more complex problems.
