Itu jawaban yang eliminasix + y - 2z = -1 .. (1)
3x + y + 3z = 17 .. (2)
2x - 2y - 1 = 8 .. (3)
Eliminasi y :
(1) dan (2) kurangkan
-2x - 5z = -18 ... (4)
(1) dan (3) jumlahkan
2x + 2y - 4z = -2
2x - 2y - 1 = 8
4x - 5z = 6 ... (5)
Eliminasi z :
(4) dan (5) kurangkan
-6x = -24
x = 4 ✔
4x - 5z = 6
5z = 10
z = 2 ✔
x + y - 2z = -1
4 + y - 4 = -1
y = -1 ✔
