In this lesson, you will learn how to write and solve equations to determine how long it takes for two people to complete a job together. The example problem involves Mary and Beth vacuuming a room. By using the formula rate times time equals work, the transcript explains how to find the variable x, which represents the amount of time both Mary and Beth work together. The answer is 6 minutes, and the lesson emphasizes the importance of checking your work and not making common mistakes when solving work problems.
