Video describes the procedure of applying the elimination method to solve a system of nonlinear equations. The teacher considers the system of two equations, each of the degree of 2. Performing simple multiplication and addition, the teacher eliminates one variable and solves the modified equation for the second variable. Then the teacher substitutes the found values back to the original equation and solves it for the other variable. This allows to get all four solutions in this case. Note that there are written lessons for the similar systems in this module.
