x= y^2 + z^2........(1)
y = x^2 + z^2.......(2)
(1)-(2)
x- y = ( y^2 - x^2)
x- y = ( y - X)( y + x)
x - y = - (x - y)( y + x)
y + x = -1 ......(3)
SAME WAY
y + z= -1.....(4)
z + x= -1......(5)
(3)-(5)
y - z= 0
y = z
same way x= y, z= x
So x= y= z
put in 3
2x = -1
x= -1/2
Now
x/( x+1) + y/( y+1) +z/(z+1)
x/( x+1) + x/( x+1) + x/( x+1)
3x/x +1
3( -1/2))/ -1/2 + 1
-3/2)/ 1/2
-3
NOTE: THERE is some mistake .
I think in RHS it should be -3
Or in denominator it should be -x+1
