Write each system in augmented matrix form.

a. \(\left\{\begin{array}{l}4 x+5 y=-16 \\ 3 x+2 y=5\end{array}\\\right.\)
b. \(\left\{\begin{array}{l}x+y+z=4 \\ 3 x+2 y+z=7 \\ x-3 y+2 z=0\end{array}\right.\)
c. \(\left\{\begin{array}{l}x_{1}+2 x_{2}-5 x_{3}+x_{4}=5 \\ x_{1}-3 x_{3}+6 x_{4}=0 \\ x_{3}-3 x_{4}=-15 \\ x_{2}-5 x_{3}+5 x_{4}=2\end{array}\right.\)
