Solve the System of Linear Equations $$\begin{aligned}x + 3 y + 2 z & = 11 \\4 y + 9 z & = - 12 \\x + 7 y + 11 z & = - 1\end{aligned}$$

Multiple Choice

Solve the system of linear equations. If the system has infinitely many solutions, describe the solution with an ordered triple in terms of variable z.
- $$\begin{aligned}x + 3 y + 2 z & = 11 \\4 y + 9 z & = - 12 \\x + 7 y + 11 z & = - 1\end{aligned}$$

A) $\left( \frac { 19 z } { 4 } + 20 , - \frac { 9 z } { 4 } + 3 , z \right)$
B) $\left( - \frac { 19 z } { 4 } + 20 , - \frac { 9 z } { 4 } + 3 , z \right)$
C) $\left( \frac { 19 \mathrm { z } } { 4 } + 20 , - \frac { 9 \mathrm { z } } { 4 } - 3 , \mathrm { z } \right\}$
D) $\left( \frac { 19 z } { 4 } + 20 , \frac { 9 z } { 4 } + 3 , z \right)$
