Question
If the system of linear equations
x + y + 3z = 0
x + 3y + k2z = 0
3x + y + 3z = 0
has a non-zero solution (x, y, z) for some k $ \in $ R, then x + $\left( {{y \over z}} \right)$ is equal to :
x + y + 3z = 0
x + 3y + k2z = 0
3x + y + 3z = 0
has a non-zero solution (x, y, z) for some k $ \in $ R, then x + $\left( {{y \over z}} \right)$ is equal to :
