Solving an equation with variables on both sides one solution

The video tutorial explains how to solve an equation with variables on both sides. It begins by introducing the equation and the goal of isolating the variable. The instructor then demonstrates how to eliminate one of the variables by subtracting it from both sides, emphasizing the importance of performing operations on both sides of the equation. Finally, the tutorial shows how to solve the simplified equation by isolating the variable, resulting in the solution Q equals 6.
