x + 2y + 3z = a 2x +5y + 3z = b x + 8z = c what is condition should a,b,c be so that this system: a) have exact one solution b) have no solution c) have infinit number of solution please explain it step by step i really need it. thanks

The determinant of the system is equal to -1, so the system has only one solution, $\displaystyle \forall a,b,c$
i dont quite get what you mean, can you make it a little clearer ? thx
