Solving a one step equation using subtraction

The video tutorial guides viewers through solving a one-step equation by isolating the variable. It emphasizes understanding equivalent equations and properties of equality. The instructor demonstrates using inverse operations to isolate the variable, ensuring the same operation is applied to both sides of the equation to maintain equivalence. The solution is reached by subtracting 9 from both sides, resulting in the variable equaling 20.
