Use Cramer's Rule to Solve the System of Equations 9x+5y=387x2y=39\begin{array} { l } 9 x + 5 y = - 38 \\- 7 x - 2 y = 39\end{array}

Question 238

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- 9x+5y=387x2y=39\begin{array} { l } 9 x + 5 y = - 38 \\- 7 x - 2 y = 39\end{array}


A) Cramer's rule does not apply since D=0D = 0 ; \varnothing
B) {(8,6) }\{ ( - 8,6 ) \}
C) {(7,6) }\{ ( - 7,6 ) \}
D) {(7,5) }\{ ( - 7,5 ) \}
