The question appears to contain nonsensical equations. Here is a revised version that makes sense:

[tex]\[
\begin{array}{c}
0 + x = 7 \\
0 - x = 1 \\
x = 7 + 3 - 5 \\
0 + x = 9
\end{array}
\][/tex]

Let's tackle the given system of equations step-by-step.

1. Consider the first equation:
[tex]\[ +-0 = 7 \][/tex]
This equation does not make sense, because [tex]\(+0\)[/tex] is always equal to 0, not 7. Thus, there might be a mistake in the formulation of this equation.

2. Consider the second equation:
[tex]\[ -0 = 1 \][/tex]
Similarly, this equation does not make sense because [tex]\(-0\)[/tex] is always equal to 0, not 1. Again, this suggests a potential mistake in the equation.

3. Let's move to the third equation:
[tex]\[ \} = 7 + 3 - 5 \][/tex]
Here, we will perform the arithmetic operations step-by-step:
[tex]\[ 7 + 3 = 10 \][/tex]
[tex]\[ 10 - 5 = 5 \][/tex]
Therefore, the result is 5.

4. Consider the fourth equation:
[tex]\[ 0 + \xi = 9 \][/tex]
To solve for [tex]\(\xi\)[/tex], isolate [tex]\(\xi\)[/tex] on one side of the equation:
[tex]\[ \xi = 9 \][/tex]

So, in summary:
- The complicated equations (1 and 2) appear to be incorrect.
- The third equation results in 5.
- The solution for [tex]\(\xi\)[/tex] in the fourth equation is 9.

Thus, the results from the system of equations are:
[tex]\[ (5, 9) \][/tex]
