Solving and Verifying Equations

The video tutorial explains how to solve simple algebraic equations. It begins with solving the equation 2X = 20 by simplifying and finding the value of X. The solution is verified by checking if the equation balances. A new equation, 3X = 24, is introduced as a challenge, and the steps to solve it are demonstrated. The tutorial emphasizes understanding the process of solving equations and verifying solutions.
