The video tutorial covers the sixth-grade math concept of determining the validity of equations and inequalities, specifically focusing on Texas standard 6.10b. Using a problem from the 2019 released STAAR test, the instructor demonstrates two methods to solve inequalities: substitution and isolating the variable. The substitution method involves replacing the variable with a given value, while isolating the variable requires manipulating the equation to solve for the variable. The tutorial concludes with identifying the correct inequality solution.
