Solve the system of equations below. Homework Help ✎

x + 3y = 16
x − 2y = 31

The answer for the linear system is (25, −3).

  1. Now rewrite the system and replace with .

    x2 + 3y = 16
    x2 − 2y = 31

  2. What effect will this have on the solution to the system? Solve the new system.

    Since x2 replaced x and you already know the solution for x, what does x2 equal?

    The equations represent parabolas that intersect at two points.
