To solve the equation \( 102.5(x - 11.92) = 71.6 \), we first divide both sides by 102.5:
\[ x - 11.92 = \frac{71.6}{102.5} \]
Calculating the right-hand side:
\[ \frac{71.6}{102.5} \approx 0.698048 \]
Now we add \( 11.92 \) to both sides:
\[ x = 11.92 + 0.698048 \]
Calculating that:
\[ x \approx 12.618048 \]
Rounding to three decimal places gives:
\[ x \approx 12.618 \]
So the answer is \(\boxed{12.618}\).
