Jawab:
xyz = 3.1.2 = 6 = B
Penjelasan dengan langkah-langkah:
3/x = 9 - 5/y - 6/z
6/x = 18 - 10/y - 12/z
18 - 10/y -12/z + 3/y + 4/z = 7
Persamaan ke 1 -7/y - 8/z = -11
9 - 5/y - 6/z + 4/y + 2/z = 6
Persamaan ke 2 - 1/y - 4/z = -3
Hitung menggunakan metode eleminasi
-7/y - 8/z = - 11 x1 -7/y - 8/z = -11
-1/y - 4/z = -3 x2 -2/y - 8/z = -6
__________-
- 5/y = -5
y = 1
Gunakan subtisusi
-1/1 - 4/z = -3
-1 - 4/z = -3
-4/z = -2
z = 2
3/x + 4/y + 2/z = 6
3/x + 4/1 + 2/2 = 6
3/x + 4 + 1 = 6
3/x = 1
x = 3
xyz= 6
