This video tutorial demonstrates how to solve simultaneous nonlinear equations using the substitution method. The first equation represents a circle, and the second a hyperbola. The video shows the graphical intersection of these equations and proceeds to solve them algebraically. By substituting and simplifying, the values of y are found, followed by back substitution to determine the corresponding x values. The final solution set consists of four ordered pairs, representing the intersection points of the circle and hyperbola.
