Tentukan SPLTV dari1/x + 2/y – 3/z = -102/x – 1/y + 3/z = 181/x + 3/y – 1/z = 8
Penjelasan dengan langkah-langkah:
1/x + 2/y – 3/z = -10
2/x – 1/y + 3/z = 18
1/x + 3/y – 1/z = 8
x+2y-3z=-10 (1)
2x-y+3z=18. (2)
x+3y-z=8. (3)
Eliminasi X pers 1 dan 2
x+2y-3z=-10 x2
2x-y+3z=18. x1
2x+4y-6z=-20
2x-y+3z=18
5y-9z=-38. (3)
eliminasi X pers 2 dan 3
2x-y+3z=18. x1
x+3y-z=8. x2
2x-y+3z=18
2x+6y-2z=16
-7y+5z=2. (4)
eliminasi y pers 3 dan 4
5y-9z=-38. x7
-7y+5z=2. x5
