Materi : SPLTV
Kelas : X SMA
x + y + z = 1 ........... 1)
2x - y + 3z = 2 ........ 2)
2x - 4y - z = 2 .......... 3)
2x - y + 3z = 2
2x - 4y - z = 2
----------------------- -
3y + 4z = 0
x + y + z = 1 .......... ×2
2x -y + 3z = 2 ......... ×1
-------------------------------
2x + 2y + 2z = 2
2x - y + 3z = 2
--------------------------- -
-y - z = 0
3y + 4z = 0 .... ×1
-y - z = 0 ......... ×3
-----------------------------
3y + 4z = 0
-3y - 3z =0
---------------------------- +
z = 0
-y - z = 0
-y - 0 = 0
-y = 0
y = 0
x + y + z = 1
x + 0 + 0 = 1
x = 1
Hp = {1 , 0 , 0 }
