\(A\) is the point \((4,-2)\) and the line \(AB\) is parallel to the line \(\frac{1}{2}x-3y=9\).

The equation of the line \(BC\) is \(2x+9y+52=0\).
Find the \(x\)-coordinate of \(B\).


It is given that \(\overrightarrow{AD}=\begin{pmatrix} 3\\3 \end{pmatrix}\) and \(\overrightarrow{AE}=\begin{pmatrix} 5 \\ 1 \end{pmatrix}\).
