To solve the equation \( 4|7 - x| + 1 = -1 \), we first isolate the absolute value expression.
1. Subtract 1 from both sides:
\[
4|7 - x| + 1 - 1 = -1 - 1 \\
4|7 - x| = -2
\]
2. Divide both sides by 4:
\[
|7 - x| = -\frac{1}{2}
\]
The absolute value of any expression cannot be negative. Since \( |7 - x| \) is defined to be non-negative (it represents a distance), this means that the equation \( |7 - x| = -\frac{1}{2} \) has no solution.
Thus, the final answer is:
**no solution**
