Solve using elimination. x = 5, y = 9; x = -5, y = 9; x = 5, y = -9; x = -5, y = -9 or (5, 9), (-5, 9), (5, -9), (-5, -9) b.

Solve using elimination.

    a. x = 5, y = 9; x = -5, y = 9; x = 5, y = -9; x = -5, y = -9 or (5, 9), (-5, 9), (5, -9), (-5, -9)

   b. x = 5, y = 9; x = 9, y = 5; x = -5, y = -9; x = -9, y = -5 or (5, 9), (9, -5), (-5, -9), (-9, -5)

   c. x = -5, y = -9; x = -9, y = -5 or (-5, -9), (-9, -5)

   d. x = 5, y = -9; x = 5, y = 9 or (5, -9), (5, 9)
