Understanding Equations and the Story of X

The video tutorial covers solving equations by telling the 'story of X'. It includes two examples: one with the equation 2(X + 1) - 3 = 5 and another with (3X - 4)/2 = 7. Each example is solved by constructing the equation step-by-step and then solving it by reversing the operations. The solutions are verified by substituting the values back into the original equations.
