Solve the system by the addition method. If there is no solution or an infinite number of solutions, so state. Use set
notation to express the solution set.
-$$\left\{ \begin{array} { l }
9 x + 5 y = 51 \
7 x - 2 y = 75
\end{array} \right.$$
A) no solution; $\varnothing$
B) $\{ ( 9 , - 6 ) \}$
C) $\{ ( 9 , - 5 ) \}$
D) $\{ ( 8 , - 5 ) \}$
