In this MinuteMath video, Sean Gann explains how to solve literal equations by isolating a specific variable. The example used is G = CA - B, which is solved for A. The process involves rewriting the equation, adding B to both sides, and dividing by C to isolate A. The final solution is A = (G + B) / C. The video concludes with a recap of the steps taken to reach the solution.
