We have the following:

1.


\begin{gathered} 3x-2y=5 \\ 3x-2y=16 \\ _{}---------- \\ 3x-3x-2y+2y=5-16 \\ 0=-11 \end{gathered}

Therefore, the system has no solution

2.


\begin{gathered} 3x-y=7 \\ 3x-y=7 \\ -------- \\ 3x-3x-y+y=7-7 \\ 0=0 \end{gathered}

Therefore, the system has infinite solutions
