Tentukan sistem pertidak samaan yang memenuhi daerah penyelesaian berikut : 24x+8y=320 26x+16y=200

24x + 8y = 320        x2  = 48x + 16y = 640

-26x + 16y = 200      x1  = 26x + 16y = 200     -

                                                22x              = 440

                                                                X   = 440/22

                                                                      = 20

24x + 8y = 320                                                          Jadi, x = 20 dan y = (-20)

(24x20) +8y = 320

(480) + 8y = 320

8y = 320 – 480

8y = (-160)

Y   =  (-160) : 8 = -20
