The video tutorial explains how to solve an equation involving powers of nine. It begins by simplifying the equation by dividing both sides by two. Then, it rewrites the numbers as powers of three, allowing the equation to be expressed in terms of exponents. Finally, it solves for x by equating the exponents and dividing both sides by two, resulting in x equaling three halves.
