In this video, Sean Gannon from MinuteMath teaches how to solve literal equations by isolating variables. The example used is g = x * c, where the goal is to solve for x. The process involves rewriting the equation and dividing both sides by c to isolate x, resulting in x = g/c. The video concludes with a recap of the steps taken to reach the solution.
