Himpunan penyelesaian sistem persamaan : 1/x + 1/y - 1/z = 4 2/x - 3/y + 1/z = 0 1/x - 1/y = -2 Adalah...

Jadi, karena 1/x = 8 maka x = 1/8. 1/y = 10 jadi, y = 10 dan 1/z = 14 jadi z = 1/14
HP ={(1/8, 1/10, 1/14}

1/x + 1/y - 1/z = 4
2/x -3/y + 1/z = 0
----------------------- +
3/x - 2/y = 4 dari 1/x-1/y = -2. (kali 2)
2/x - 2/y = -4
----------------- -
1/x = 8
x = 1/8
dari 1/x-1/y= -2
1/(1/8) -1/y = -2
8 - 1/y = -2
-1/y = -10
y = 1/10
1/x + 1/y - 1/z = 4
1/(1/8) + 1/(1/10) -1/z = 4
8 +10 - 1/z = 4
1/z = 14
z = 1/14
HP = {1/8, 1/10, 1/14 }
