4 x + 3 y = 3 \
2 x + y = - 1
\end{array} \right.$$
A) $( - 3,5 )$
B) $( - 5 , - 3 )$
C) $( 5 , - 3 )$
D) $( 3 , - 5 )$

Quizplus · Accepted Answer

Cramer's rule can be used to solve the system of equations. The determinant of the coefficient matrix is not zero, so the system has a unique solution. The solution is $ ( - 3,5 ) $.
