What are the systems of equations shown in the image?

The image shows two systems of linear equations:

1. \[ \begin{cases} \sqrt{2}x - y = -6 \\ 3x + 5y = 17 \end{cases} \]
2. \[ \begin{cases} 5x + 2y = -12 \\ 3x - 4y = -2 \end{cases} \]
3. \[ \begin{cases} 2x + y = 4 \\ 5x - 3y = -12 \end{cases} \]
