Answer
$(x,y)=(4,0)$; dependent equation
Work Step by Step
Need to apply Cramer's Rule.
$x=\dfrac{D_x}{D}$; $y=\dfrac{D_y}{D}$
Now, $D=\begin{vmatrix}1&-3\\3&-4\end{vmatrix}=-4+9=5$;
$D_x=\begin{vmatrix}4&-3\\12&-4\end{vmatrix}=-16+36=20$;
$D_y=\begin{vmatrix}1&4\\3&12\end{vmatrix}=12-12=0$
Thus, $x=\dfrac{20}{5}=4$ and $y=0$
Hence, $(x,y)=(4,0)$; dependent equation
