The image shows a mathematical problem that asks for the solution to a system of equations. The specific problem seems to require identifying one of the values of $x$ in the equation given.

The key part of the problem appears to be the square root expression:

$\sqrt{\frac{2x - 5}{x}} = 2$

To solve for $x$, we can proceed as follows:

1. Square both sides to eliminate the square root:

   $\left(\sqrt{\frac{2x - 5}{x}}\right)^2 = 2^2$

   This simplifies to:

   $\frac{2x - 5}{x} = 4$

2. Multiply both sides by $x$ to eliminate the fraction:

   $2x - 5 = 4x$

3. Rearrange the equation to solve for $x$:

   $2x - 4x = 5$

   Simplifying further:

   $-2x = 5$

   So:

   $x = -\frac{5}{2}$

This value does not appear directly in the options given, so it may be necessary to check for extraneous solutions or consider any other constraints implied by the problem.

Since the problem asks for "uno de los valores de $x$," and considering possible integer results from the original equation after checking the steps, the correct answer is not explicitly clear based on this calculation alone. However, typically, such problems expect integer results.

Would you like a more detailed check or further exploration of the system?
