If the System Has Infinitely Many Solutions, Write the Solution $$\begin{array} { l } 7 x - 6 y = 1 \\- 14 x + 12 y = 1\end{array}$$

If the system has infinitely many solutions, write the solution set with x arbitrary.
- $$\begin{array} { l } 7 x - 6 y = 1 \\- 14 x + 12 y = 1\end{array}$$

A) $\left\{ \left( x , \frac { 1 } { 8 } x \right) \right\}$

B) $\left\{ \left\{ x , \frac { 1 } { 3 } + \frac { 7 } { 6 } x \right) \right\}$

C) $\varnothing$

D) $\left\{ \left\{ - \frac { 1 } { 8 } , \frac { 5 } { 16 } \right) \right\}$
