The video tutorial explains how to solve functions for a given output. It covers two examples: solving f(x) = -x - 5 when f(x) = -6, and solving f(x) = 5x - 3 when f(x) = 7. The instructor demonstrates the use of inverse operations to isolate the variable x, emphasizing the importance of maintaining equality by performing operations on both sides of the equation.
