Multiple Choice

Solve the system of linear equations by the method of elimination.Find (r,s) and check your solution algebraically. $\left\{ \begin{array} { c } 2 r + 4 s = 7 \\16 r + 50 s = 77\end{array} \right.$

• A) \(\left( \frac { 7 } { 6 } , - \frac { 7 } { 6 } \right)\)
• B) \(( 7,77 )\)
• C) \(\left( \frac { 7 } { 6 } , \frac { 7 } { 6 } \right)\)
• D) \(\left( - \frac { 7 } { 6 } , \frac { 7 } { 6 } \right)\)
• E) \(\left( - \frac { 7 } { 6 } , - \frac { 7 } { 6 } \right)\)
