Use the Gauss-Jordan method to solve the system of equations. If the system has infinitely many solutions, let the last
variable be the arbitrary variable.
-$$\begin{array} { c }
4 x - 3 y + 6 z = - 5 \
8 x + 4 y - 8 z = - 5 \
20 x - 15 y + 30 z = - 1
\end{array}$$
A) $\{ ( - 5 z + 4,4 z - 15 , z ) \}$
B) $\{ ( 5,5 , - 1 ) \}$
C) $\varnothing$
D) $\{ ( - 5 , - 5 , - 1 ) \}$
