Add Math F4 ( Persamaan Serentak )

Selesaikan persamaan serentak yang berikut:

x + 3y = 1, x² + 2xy = y² + 7

• x = -8 , y = 3

  x = 4 , y = -1

• x = 8, y = -3

  x = -4, y = 1

Selesaikan persamaan berikut :

3x - 4y = x² + y² - 5 = 6x - 2y -11

• x = 3, y = 1

  x = 63/13 , y = 23/13

• x = -3, y = -1

  x = 63/13 , y = 23/13
