We consider the system given by the following augmented matrix \( \left[\begin{array}{rrr|r}2 & 1 & -3 & 2 \\ 2 & -3 & 1 & 10 \\ -2 & 1 & 1 & -6\end{array}\right] \) Is there a value of \( \alpha \) such that \( z=\alpha, y=1, z=3 \) is a solution of the system? Choose the correct value of \( \alpha \). None of the given options are correct \( \alpha=-4 \) \( \alpha=4 \) \( \alpha=5 \) \( \alpha=-5 \)
