Find all positive real numbers x,y,z such that 2x-2y+1/z=1/2024,2y-2z+1/x=1/2024,2z-2x+1/y=1/2024

We are given the system of three equations:

\[
2x - 2y + \frac{1}{z} = \frac{1}{2024}
\]
\[
2y - 2z + \frac{1}{x} = \frac{1}{2024}
\]
\[
2z - 2x + \frac{1}{y} = \frac{1}{2024}
\]

Our goal is to find all positive real numbers \(x\), \(y\), and \(z\) that satisfy this system of equations.

### Step 1: Add all three equations

We begin by adding all three equations together:

\[
(2x - 2y + \frac{1}{z}) + (2y - 2z + \frac{1}{x}) + (2z - 2x + \frac{1}{y}) = \frac{1}{2024} + \frac{1}{2024} + \frac{1}{2024}
\]

Simplifying the left-hand side:

\[
(2x - 2y + 2y - 2z + 2z - 2x) + \left( \frac{1}{z} + \frac{1}{x} + \frac{1}{y} \right) = \frac{3}{2024}
\]

The terms involving \(x\), \(y\), and \(z\) cancel out:

\[
\frac{1}{x} + \frac{1}{y} + \frac{1}{z} = \frac{3}{2024}
\]

Thus, we have the first key equation:

\[
\frac{1}{x} + \frac{1}{y} + \frac{1}{z} = \frac{3}{2024}
\]

### Step 2: Assume symmetry

Given that the equations for \(x\), \(y\), and \(z\) are symmetrical in form, a natural assumption is that \(x = y = z\). Let's verify this.

### Step 3: Solve under the assumption \(x = y = z\)

Substituting \(x = y = z\) into the equation from Step 1:

\[
\frac{1}{x} + \frac{1}{x} + \frac{1}{x} = \frac{3}{2024}
\]

Simplifying:

\[
\frac{3}{x} = \frac{3}{2024}
\]

Solving for \(x\):

\[
x = 2024
\]

Since \(x = y = z\), we have \(x = y = z = 2024\).

### Step 4: Verify the solution

We now verify that \(x = y = z = 2024\) satisfies the original system of equations.

Substitute \(x = y = z = 2024\) into the first equation:

\[
2(2024) - 2(2024) + \frac{1}{2024} = \frac{1}{2024}
\]

This is true. The same verification holds for the other two equations.

Thus, the only solution is \(x = y = z = 2024\).

### Conclusion:

The only positive real solution is:
\[
x = y = z = 2024
\]
