## Intermediate Algebra for College Students (7th Edition)

Need to apply Cramer's Rule. $x=\dfrac{D_x}{D}$; $y=\dfrac{D_y}{D}$ Now, $D=\begin{vmatrix}3&3\\2&2\end{vmatrix}=6-6=0$; $D_x=\begin{vmatrix}2&3\\3&2\end{vmatrix}=4-9=-5$; $D_y=\begin{vmatrix}3&2\\2&3\end{vmatrix}=9-4=5$ Thus, $x=\dfrac{-5}{0}$ and $y=\dfrac{5}{0}$ Hence,inconsistent equations; parallel lines.
