Mathematics - Determinant Question with Solution | TestHub

If$a=-3,$then the system has infinitely many solutions for all values of$\lambda$and$\mu$

If$a \ne -3,$then the system has a unique solution for all values of$\lambda$and$\mu$

If$\lambda +\mu =0,$then the system has infinitely many solutions for$a=-3$

If$\lambda +\mu \ne 0,$then the system has no solution for$a=-3$
