Matematika 2x - y = 2 x + 2y = 6

heathboehmulv – March 12, 2023

2x - y = 2
x + 2y = 6

Dieliminasikan nilai x, maka tentukan nilai y.

2x - y = 2 >>>>>>>>>>> dikalikan 1

x + 2y = 6 >>>>>>>>>>> dikalikan 2

2x - y = 2

2x + 4y = 12 _

-5y = -10

y = (-10)/(-5)

y = 2

Dieliminasikan nilai y, maka tentukan nilai x.

2x - y = 2 >>>>>>>>>>> dikalikan (-2)

x + 2y = 6 >>>>>>>>>>> dikalikan 1

-4x + 2y = -4

x + 2y = 6 _

-5x = -10

x = (-10)/(-5)

x = 2

Jadi, himpunan penyelesaian tersebut adalah {x , y} = {2 , 2}.
