Answer
The solutions are $d=54$ and $d=-54$.
The graph is shown below.
Work Step by Step
The given equation is
$\Rightarrow |\frac{d}{9}|=6$
Write related linear equations.
$\Rightarrow \frac{d}{9}=6$ or $\frac{d}{9}=-6$
Multiply each side by $9$.
$\Rightarrow 9\cdot \frac{d}{9}=9\cdot 6$ or $9\cdot \frac{d}{9}=9\cdot (-6)$
Simplify.
$\Rightarrow d=54$ or $d=-54$
The solutions are $d=54$ and $d=-54$.
