We are given the equation:

\[
\log_e(8x + 6) = -1
\]

This is a logarithmic equation, and \( \log_e \) is the natural logarithm, often denoted as \( \ln \). To solve for \( x \), follow these steps:

### Step 1: Rewrite the equation in exponential form
The logarithmic equation can be rewritten as an exponential equation. The general rule is:

\[
\log_b(a) = c \implies a = b^c
\]

In our case:

\[
\ln(8x + 6) = -1 \implies 8x + 6 = e^{-1}
\]

### Step 2: Simplify the exponential
We know that \( e^{-1} = \frac{1}{e} \). Therefore, the equation becomes:

\[
8x + 6 = \frac{1}{e}
\]

### Step 3: Solve for \( x \)
Now, isolate \( x \) by following these steps:

1. Subtract 6 from both sides:
   \[
   8x = \frac{1}{e} - 6
   \]

2. Simplify the right-hand side:
   \[
   8x = \frac{1}{e} - \frac{6e}{e} = \frac{1 - 6e}{e}
   \]

3. Divide both sides by 8:
   \[
   x = \frac{1 - 6e}{8e}
   \]

Thus, the solution is:

\[
x = \frac{1 - 6e}{8e}
\]
