Answer
The equation has no solution.
Work Step by Step
The given equation is
$\Rightarrow -4|8-5n|=13$
Divide each side by $-4$.
$\Rightarrow \frac{-4|8-5n|}{-4}=-\frac{13}{4}$
Simplify.
$\Rightarrow |8-5n|=-\frac{13}{4}$
The absolute value of an expression must be greater than or equal to zero.
The expression $|8-5n|$ cannot equal $-\frac{13}{4}$.
So, the equation has no solution.
