Use Cramerʹs Rule to Solve the System of Equations $$\begin{array} { l } 5 x - 7 y = 30 \\2 x - 5 y = 12\end{array}$$

Multiple Choice

Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } 5 x - 7 y = 30 \\2 x - 5 y = 12\end{array}$$

A) $\{ ( 6,1 ) \}$
B) $\{ ( 6,0 ) \}$
C) $\{ ( 5,1 ) \}$
D) Cramer's rule does not apply since $\mathrm { D } = 0 ; \varnothing$
