Solve the System $$\begin{array} { l } 2 x + 8 y = 7 \\4 x + 16 y = 5\end{array}$$

Multiple Choice

Solve the system. If the system has infinitely many solutions, write the solution set with x arbitrary.
- $$\begin{array} { l } 2 x + 8 y = 7 \\4 x + 16 y = 5\end{array}$$

A) $\left\{ \left( x , \frac { 1 } { 2 } - \frac { 1 } { 4 } x \right) \right\}$
B) $\left\{ \left( x , \frac { 7 } { 8 } - \frac { 1 } { 4 } x \right) \right\}$
C) $\{ ( 0,0 ) \}$
D) $\varnothing$
