Page 1 of 2 10.7 Solving Quadratic Systems 633 Solving a System by Substitution Find the points of intersection of the graphs in the system. Solve the system by graphing. Systems of Linear and Quadratic Equations Lessons 7-1, 7-2, and 10-4 1. In Lesson 7-1, you solved systems of linear equations graphically and algebraically. But what about a system of two equations where one equation is linear, and the other is quadratic? x2+ 4y2º 4 = 0 Equation 1 º2y2+ x + 2 = 0 Equation 2 SOLUTION Because Equation 2 has no x2-term, solve that equation for x. º2y2+ x + 2 = 0 x = 2y2º 2 Next, substitute 2y2 º2for x in Equation 1 and solve for y. x2+ 4y2º 4 = 0 Equation 1 Given the equation for this parabola have a maximum or minimum value for x form ) this.
