The video tutorial explains how to solve an inequality involving the absolute value of y plus 22 being less than or equal to 13.5. The process involves isolating the absolute value on one side and simplifying the inequality. However, it is shown that the absolute value cannot be less than or equal to a negative number, leading to the conclusion that there is no solution to the problem.
