The video tutorial explains how to solve an equation by rewriting 9 as 3 squared and simplifying the expression by adding exponents. It demonstrates that when the bases are the same, the exponents must be equal, leading to an equation involving the absolute value of x. By solving this equation, the tutorial shows that the absolute value of x equals 1, resulting in x being either positive or negative one.
