If the System Has Infinitely Many Solutions, Write the Solution

Multiple Choice

If the system has infinitely many solutions, write the solution set with x arbitrary.
- $$\begin{array} { l } \frac { 3 } { x } + \frac { 8 } { y } + \frac { 1 } { z } = - \frac { 2 } { 3 } \\\frac { 8 } { x } + \frac { 1 } { y } - \frac { 8 } { z } = \frac { 61 } { 24 } \\\frac { 1 } { x } + \frac { 1 } { y } + \frac { 4 } { z } = - \frac { 5 } { 8 }\end{array}$$

A) $\{ ( 6 , - 8 , - 6 ) \}$

B) $\left\{ \left\{ \frac { 1 } { 6 } , - \frac { 1 } { 8 } , - \frac { 1 } { 6 } \right) \right\}$

C) $\left\{ \left\{ \left( \frac { 1 } { 6 } , - \frac { 1 } { 8 } , \frac { 1 } { 6 } \right) \right\} \right.$

D) $\{ ( 6 , - 8,6 ) \}$
