Jika 6/(x+2) + 15/(y+3) + 2/(z+1) = 8
4/(x+2) + 5/(y+3) + 3/(z+1) = 6
8/(x+2) - 10/(y+3) + 5/(z+1) = 5
Tentukan nilai x,y,z !

1/(x+2) = a
1/(y+3) = b
1/(z+1) = c
Jadi,
6a+15b+2c=8
4a+5b+3c=6
8a-10b+5c=5
Itung aja ya sendiri,
Dapetnya
a = 9/46, b = 33/115, c = 29/23
1/(x+2) = 9/46 -> x+2=46/9 -> x = 46/9 - 2 -> x = 28/9
1/(y+3) = 33/115 -> y+3 = 115/33 -> y = 115/33 - 3 -> y = 16/33
1/(z+1) = 29/23 -> z+1 = 23/29 -> z = 23/29 - 1 -> z = -6/29
Angkanya gak bagus nih
