137 = \frac{(35 - 4) \cdot 2 \pi}{\frac{1}{10 \cdot (1.05 + x)} + \ln\left(\frac{1.05 + x}{1.05}\right) \cdot \frac{1}{0.02} + \ln\left(\frac{1.05}{1.02375}\right) \cdot \frac{1}{13.8} + \frac{1}{45.99 \cdot 1.02375} + \ln\left(\frac{1.02375}{0.9975}\right) \cdot \frac{1}{13.8} + \frac{1}{29.92 \cdot 0.9975}}

To solve for \( x \) in the equation:

\[
137 = \frac{(35 - 4) \cdot 2 \pi}{\frac{1}{10 \cdot (1.05 + x)} + \ln\left(\frac{1.05 + x}{1.05}\right) \cdot \frac{1}{0.02} + \ln\left(\frac{1.05}{1.02375}\right) \cdot \frac{1}{13.8} + \frac{1}{45.99 \cdot 1.02375} + \ln\left(\frac{1.02375}{0.9975}\right) \cdot \frac{1}{13.8} + \frac{1}{29.92 \cdot 0.9975}}
\]

we can proceed as follows:

1. **Evaluate the constants and the logarithmic terms**: First, calculate the constants in the denominator, particularly the terms that do not depend on \( x \), such as \( \ln\left(\frac{1.05}{1.02375}\right) \), \( \ln\left(\frac{1.02375}{0.9975}\right) \), \( \frac{1}{45.99 \cdot 1.02375} \), and \( \frac{1}{29.92 \cdot 0.9975} \).

2. **Isolate terms with \( x \)**: Rewrite the equation by isolating the terms that include \( x \), which are:
   - \( \frac{1}{10 \cdot (1.05 + x)} \)
   - \( \ln\left(\frac{1.05 + x}{1.05}\right) \cdot \frac{1}{0.02} \)

3. **Numerical approach to solve for \( x \)**: Due to the complexity of the expression, using a numerical solver is likely the most efficient approach after simplifying the constants. 

### Step-by-Step Outline
1. Substitute simplified values for the constants.
2. Rearrange the equation to isolate \( x \)-dependent terms.
