Kak tolong dibantu besok dikumpulkan X-2y-2=0 2x-2y-4=0 Dengan cara eliminasi

x - 2y - 2 = 0 || ×2
2x - 2y - 4 = 0 || ×1
2x - 4y - 4 = 0
2x - 2y - 4 = 0
___________ _
0x - 2y - 4 = 0
-2y = 0 + 4
-2y = 4
y = 4 ÷ -2
y = -2.

y = -2 eliminasi ke pers. x
x - 2y - 2 = 0
x - 2 (-2) - 2 = 0
x + 4 - 2 = 0
x + 2 = 0
x = 0 - 2
x = -2.
