Solve the System by the Addition Method $$\left\{ \begin{array} { l } - 5 x + 4 y = - 6 \\8 y = - 12 + 10 x\end{array} \right.$$

Multiple Choice

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.
- $$\left\{ \begin{array} { l } - 5 x + 4 y = - 6 \\8 y = - 12 + 10 x\end{array} \right.$$

A) $\{ ( 0,0 ) \}$
B) $\{ ( - 5,4 ) \}$
C) no solution; $\varnothing$
D) infinitely many solutions; $\{ ( x , y ) \mid - 5 x + 4 y = - 6 \}$ or $\{ ( x , y ) \mid 8 y = - 12 + 10 x \}$
