The problem asks to **find the equation of a circle with radius 5**, where the center of the circle lies on the **x-axis** and the circle passes through the point **(2, 3)**.

### Step-by-Step Solution:
1. **General equation of a circle**:
   The general form of the equation of a circle is:
   \[
   (x - h)^2 + (y - k)^2 = r^2
   \]
   where \((h, k)\) is the center of the circle and \(r\) is the radius.

2. **Given information**:
   - The radius of the circle is \(5\), so \(r = 5\).
   - The center of the circle lies on the x-axis, meaning \(k = 0\). Therefore, the center is at \((h, 0)\).
   - The circle passes through the point \((2, 3)\).

3. **Substitute into the circle equation**:
   We substitute the given values into the circle equation:
   \[
   (x - h)^2 + (y - 0)^2 = 5^2
   \]
   which simplifies to:
   \[
   (x - h)^2 + y^2 = 25
   \]

4. **Use the point (2, 3)**:
   Since the point \((2, 3)\) lies on the circle, we substitute \(x = 2\) and \(y = 3\) into the equation:
   \[
   (2 - h)^2 + 3^2 = 25
   \]
   Simplifying:
   \[
   (2 - h)^2 + 9 = 25
   \]
   \[
   (2 - h)^2 = 16
   \]

5. **Solve for \(h\)**:
   Taking the square root of both sides:
   \[
   2 - h = \pm 4
   \]
   This gives two possible values for \(h\):
   \[
   h = 2 - 4 = -2 \quad \text{or} \quad h = 2 + 4 = 6
   \]

6. **Equations of the circle**:
   Thus, the center of the circle can be either \((-2, 0)\) or \((6, 0)\). Therefore, we have two possible equations for the circle:

   **For \(h = -2\):**
   \[
   (x + 2)^2 + y^2 = 25
   \]
   
   **For \(h = 6\):**
   \[
   (x - 6)^2 + y^2 = 25
   \]

So, the equation of the circle can be either \((x + 2)^2 + y^2 = 25\) or \((x - 6)^2 + y^2 = 25\).
