The system of equations you are referring to is incorrectly joined. I see multiple systems of equations in the image. Let me break it down:

1)
\[
\begin{cases}
2x - 5y = 9 \\
-3x + y = -5
\end{cases}
\]

2)
\[
\begin{cases}
\frac{1}{3}x - \frac{1}{2}y = 1 \\
\frac{2}{5}x + \frac{1}{4}y = \frac{3}{2}
\end{cases}
\]

3)
\[
\begin{cases}
2x + 3(x + 1) - y = 5 \\
x - 2(x + y) = 9
\end{cases}
\]

4)
\[
\begin{cases}
\sqrt{x + 3} - \sqrt{y - 1} = -3 \\
-2\sqrt{x + 3} + 3\sqrt{y - 1} = -6
\end{cases}
\]

5)
The fifth section is not a system of equations, but rather two rational expressions:
\[
\frac{2}{\sqrt{x-x}} - \frac{3u}{\sqrt{x-x}} = 5
\]

\[
\frac{-3}{\sqrt{x-x}} + \frac{4y}{5+y}
\]

These are systems and expressions; if you need help with any specific one, let me know!
