If `x, y, z` are three unequal non-zero real numbers andsatisfy the relation `(2+y)/y=1/(y-x)+1/(y-z)+1`, then

If a, b, c are non-zero real numbers and if the equations (a-1) x = y +z, (b-1) y = z + x , (c - 1) z = x + y have a non-trival solution, then ab+bc+ca=

If a , b , c are non-zero real numbers and if the system of equations (a-1)x=y+z , (b-1)y=z+x , (c-1)z=x+y has a non-trivial solution, then prove that a b+b c+c a=a b c

If a ,b ,c are non -zero real numbers and if the system of equations (a-1) x=y+z,(b-1)y=z+x,(c-1) z=x+y has a non -trivial solution, then prove that ab+bc+ca =abc .

If a , b , c are non-zero real numbers and if the system of equations (a-1)x=y=z (b-1)y=z+x (c-1)z=x+y has a non-trivial solution, then prove that a b+b c+c a=a b c

If a,b and c are non-zero real numbers and if the equation (a-1)x=y+z,(b-1)y=z+x, (c-1)z=x+y has a non-trival solution then ab+bc+ca equals to
