To solve the equation \(| \frac{b}{2} | + 5 = -7\), we first isolate the absolute value:
\[ | \frac{b}{2} | + 5 = -7 \]
Subtracting 5 from both sides gives:
\[ | \frac{b}{2} | = -7 - 5 \] \[ | \frac{b}{2} | = -12 \]
Since the absolute value of any number is always non-negative (i.e., it cannot be negative), there are no solutions to this equation.
Thus, the answer is:
no solution
