16. Diketahui persamaan matriks : \( \mathrm{X} \cdot\left(\begin{array}{cc}3 & 2 \\ -4 & -3\end{array}\right)=\left(\begin{array}{ll}4 & 2 \\ 3 & 1\end{array}\right), \mathrm{X} \) adalah matriks berordo \( (2 \times 2) \) maka \( \mathrm{X}=\ldots \) 17. Ditentukan matriks \( \mathrm{A}=\left(\begin{array}{rr}2 & -1 \\ 3 & 5\end{array}\right), \mathrm{B}=\left(\begin{array}{rr}4 & -3 \\ p & 1\end{array}\right) \), dan \( \mathrm{C}=\left(\begin{array}{cc}10 & -7 \\ 2 & -4\end{array}\right) \) Jika \( \mathrm{AB}=\mathrm{C} \), nilai \( \mathrm{p}=\ldots \)
