Answer
$y=\{ -7.3,7.3 \}$
Work Step by Step
$\bf{\text{Solution Outline:}}$
To solve the given equation, $
|y|=7.3
,$ use the definition of an absolute value equality.
$\bf{\text{Solution Details:}}$
Since for any $c\gt0$, $|x|=c$ implies $x=c \text{ or } x=-c,$ the given equation is equivalent to
\begin{array}{l}\require{cancel}
y=7.3
\\\\\text{OR}\\\\
y=-7.3
.\end{array}
Hence, $
y=\{ -7.3,7.3 \}
.$
