To solve the equation \( 102.5(x - 11.92) = 71.6 \), we start by isolating \( x \).
- Divide both sides by \( 102.5 \):
\[ x - 11.92 = \frac{71.6}{102.5} \]
- Calculate \( \frac{71.6}{102.5} \):
\[ \frac{71.6}{102.5} \approx 0.698541 \]
- Now, add \( 11.92 \) to both sides:
\[ x = 0.698541 + 11.92 \]
- Calculate \( x \):
\[ x \approx 12.618541 \]
- Round the answer to three decimal places:
\[ x \approx 12.619 \]
Thus, the solution to the equation is:
\[ \boxed{12.619} \]
