If \( A=\left(\begin{array}{cc}2 & 0 \\ -3 & 1\end{array}\right) \) and \( B=\left(\begin{array}{cc}-2 & 4 \\ 3 & 1\end{array}\right) \) and \( X \) is a
\( \mathrm{P} \)
matrix such that \( 3 A+4 X=5 B \), then \( X= \) ?
(1) \( \left(\begin{array}{rr}-3 & 5 \\ 6 & 2\end{array}\right) \)
(2) \( \left(\begin{array}{rr}-4 & 5 \\ 6 & \frac{1}{2}\end{array}\right) \)
(3) \( \left(\begin{array}{rr}-4 & 5 \\ 3 & 1\end{array}\right) \)
(4) \( \left(\begin{array}{ll}4 & -5 \\ 6 & -1\end{array}\right) \)
