Answer:

This system of equations has <em>no solution</em>. 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.
