Solve the System $$\begin{array} { l } 2 x + 2 y - 3 z = 3 \\- 5 x - 2 y + 5 z = 14 \\- 8 x - 2 y + 7 z = 31\end{array}$$

Multiple Choice

Solve the system. If there is more than one solution, write the general solution.
- $$\begin{array} { l } 2 x + 2 y - 3 z = 3 \\- 5 x - 2 y + 5 z = 14 \\- 8 x - 2 y + 7 z = 31\end{array}$$

A) No solution; inconsistent
B) $\{ ( - 3 , - 3 , - 5 ) \}$
C) $\left\{ \left[ x , \frac { 5 } { 4 } x + \frac { 57 } { 4 } , \frac { 3 } { 2 } x + \frac { 17 } { 2 } \mid x \right. \right.$ is any real number $\left. \} \right\}$
D) $\{ ( - 3 , - 4 , - 4 ) \}$
