Solving Equations and Verification

The video tutorial explains how to solve an equation by isolating the variable X. It begins with simplifying the equation by distributing and combining like terms. The next step involves isolating the variable by undoing operations, followed by solving for X through division. Finally, the solution is verified by substituting the value back into the original equation to ensure it satisfies the equation.
