What are the solutions for the following system? -2x^2+y=-5 y=-3x^2+5

Match each equation to the ordered pair that represents one of its solutions. 3x + 2y = 6 -5x + y = -10 x ? 4y = 8 -6x ? 5y = 30 ordered pair equation (0, -6) arrowboth (0, 3) arrowboth (4, -1) arrowboth (1, -5) arrowboth reset next unit 2 - pretest
