The video tutorial explores solving a mathematical problem using substitution. A magical bird suggests an alternative method to the elimination technique previously used. The process involves solving for one variable in terms of another and substituting it back into the original equation. The tutorial demonstrates the steps to solve for variables m and w, verifying that the substitution method yields the same result as the elimination method. The video concludes by encouraging viewers to apply the method to solve for other variables.
