x +y =4 -(1)
y +z= 1 -(2)
from 2, y= 1 - z
x + z = 1 -(3)
from 3 , x = 1 - z
putting values of x and y in (1)
we get, z = 3
putting z =3 in 2 and 3 ,
we get , x= -2 and y = -2
Hence , x= -2 , y = -2 , z = 3
y +z= 1 -(2)
from 2, y= 1 - z
x + z = 1 -(3)
from 3 , x = 1 - z
putting values of x and y in (1)
we get, z = 3
putting z =3 in 2 and 3 ,
we get , x= -2 and y = -2
Hence , x= -2 , y = -2 , z = 3
