Question

Whats the solution to the system of inequalities?
-3x-y+z=6
-3x-y+3z=0
-3z=3

Answer 1

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

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.
