Solve Using the Distributive Property

The video tutorial explains how to solve the equation 3X + 2 = 21. It begins by applying the distributive property, then isolates the variable term by subtracting 6 from both sides. The next step involves solving for X by dividing both sides by 3. Finally, the solution is verified by substituting X back into the original equation to ensure the result is correct.
