Solve the System $$\begin{array} { l } 8 x - 10 y = 1 \\- 16 x + 20 y = 1\end{array}$$

Multiple Choice

Solve the system. If the system has infinitely many solutions, write the solution set with x arbitrary.
- $$\begin{array} { l } 8 x - 10 y = 1 \\- 16 x + 20 y = 1\end{array}$$

A) $\varnothing$
B) $\left\{ \left( x , \frac { 3 } { 40 } x \right) \right\}$
C) $\left\{ \left( x , \frac { 1 } { 5 } + \frac { 4 } { 5 } x \right) \right\}$
D) $\left\{ \left( - \frac { 3 } { 40 } , \frac { 4 } { 25 } \right) \right\}$
