The problem given is:

Given \( f(x) = \frac{1 - 5x}{x + 2} \), with \( x \neq -2 \), find the value of the inverse function \( f^{-1}(-3) \).

### Solution:
To find \( f^{-1}(-3) \), we need to determine the inverse of \( f(x) \) and then substitute \( -3 \) as the input of the inverse function.

1. **Set up the function** \( f(x) = \frac{1 - 5x}{x + 2} \) and replace \( f(x) \) with \( y \):
   \[
   y = \frac{1 - 5x}{x + 2}
   \]

2. **Solve for \( x \) in terms of \( y \)**:
   Multiply both sides by \( x + 2 \) to eliminate the denominator:
   \[
   y(x + 2) = 1 - 5x
   \]
   Expand and rearrange to isolate \( x \):
   \[
   yx + 2y = 1 - 5x
   \]
   \[
   yx + 5x = 1 - 2y
   \]
   Factor out \( x \) on the left side:
   \[
   x(y + 5) = 1 - 2y
   \]
   \[
   x = \frac{1 - 2y}{y + 5}
   \]

   Thus, the inverse function is:
   \[
   f^{-1}(y) = \frac{1 - 2y}{y + 5}
   \]

3. **Evaluate \( f^{-1}(-3) \)** by substituting \( y = -3 \) into the inverse function:
   \[
   f^{-1}(-3) = \frac{1 - 2(-3)}{-3 + 5}
   \]
   Simplify the expression:
   \[
   f^{-1}(-3) = \frac{1 + 6}{2} = \frac{7}{2}
   \]

### Answer:
The value of \( f^{-1}(-3) \) is:
\[
\boxed{\frac{7}{2}}
\]

The correct answer is **(e) \( \frac{7}{2} \)**.
