Whats the solution to the system of inequalities?

-3x-y+z=6

-3x-y+3z=0

-3z=3

This system of equations has no solution. It is inconsistent.

Step-by-step explanation:

The last equation tells you z = - 1.

Substituting this value for z in the other two equations allows them to be written as ...

-3x - y = 7

-3x - y = 3

There are no values of x and y that can make both these equations true.
