In this video, Sean explains how to solve literal equations by isolating a specific variable. He demonstrates the process using the equation a = n + P, showing how to solve for n. The steps include setting up the equation, identifying operations, and isolating the variable by dividing both sides. The video concludes with a recap of the solution process and emphasizes the importance of understanding each step.
