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: $x = y = z = 2024$

Here are 5 related questions:

1. What happens if we relax the assumption that $x = y = z$?
2. How do symmetry properties simplify solving systems of equations?
3. Can systems of equations always be solved by assuming symmetry?

Tip: When solving symmetrical equations, assuming equality among variables can often simplify the process, but always verify the solution by substituting back into the original equations.
