To solve the equation \(\frac{|12 - x|}{2} = 4x\), follow these steps:

### Step 1: Eliminate the denominator.
Multiply both sides by 2 to remove the fraction:

\[
|12 - x| = 8x
\]

### Step 2: Consider the two cases for the absolute value.

**Case 1: \(12 - x \geq 0\)**
- Here, \(|12 - x| = 12 - x\).
- The equation becomes:

\[
12 - x = 8x
\]

- Solve for \(x\):

\[
12 = 9x \implies x = \frac{12}{9} = \frac{4}{3}
\]

- Check if this solution satisfies the condition \(12 - x \geq 0\):

\[
12 - \frac{4}{3} = \frac{36}{3} - \frac{4}{3} = \frac{32}{3} > 0
\]

Since the condition is satisfied, \(x = \frac{4}{3}\) is a valid solution.

**Case 2: \(12 - x < 0\)**
- Here, \(|12 - x| = -(12 - x) = x - 12\).
- The equation becomes:

\[
x - 12 = 8x
\]

- Solve for \(x\):

\[
-12 = 7x \implies x = -\frac{12}{7}
\]

- Check if this solution satisfies the condition \(12 - x < 0\):

\[
12 - \left(-\frac{12}{7}\right) = 12 + \frac{12}{7} = \frac{84}{7} + \frac{12}{7} = \frac{96}{7} > 0
\]

This condition is **not** satisfied, so \(x = -\frac{12}{7}\) is **not** a valid solution.

### Conclusion:
The only valid solution is \(x = \frac{4}{3}\).
