We are given the equation:

\[
4 + \frac{7}{x} = \frac{5}{3}
\]

### Steps to solve for \( x \):

1. **Subtract 4 from both sides**:
   \[
   \frac{7}{x} = \frac{5}{3} - 4
   \]

   To subtract 4, express it as a fraction with a denominator of 3:
   \[
   \frac{5}{3} - \frac{12}{3} = \frac{-7}{3}
   \]
   Now the equation becomes:
   \[
   \frac{7}{x} = \frac{-7}{3}
   \]

2. **Cross multiply**:
   \[
   7 \cdot 3 = -7 \cdot x
   \]
   This simplifies to:
   \[
   21 = -7x
   \]

3. **Solve for \( x \)**:
   \[
   x = \frac{21}{-7} = -3
   \]

Thus, the solution is \( x = -3 \).
