Answer
The system is inconsistent.
Work Step by Step
The system represented by the augmented matrix is
$\left\{\begin{array}{llll}
x & & & =1\\
& y & & =2\\
& & 0 & =3
\end{array}\right.$
The third equation is never satisfied - no (x,y,z) satisfies it.
There are no solutions, the system is inconsistent.
