Solving Nonlinear Equations with Elimination

The video tutorial explains how to solve a system of nonlinear equations using the elimination method. It begins with an introduction to the problem and proceeds to demonstrate the elimination method to solve for X. The tutorial then uses back substitution to find corresponding Y values, resulting in four solutions. Finally, it verifies these solutions graphically by showing the intersection points of a hyperbola and an ellipse on a coordinate plane.
