Answer
$x= \frac{y}{12}$.
Work Step by Step
The given equation is
$\Rightarrow y=4x+8x$
Use distributive property.
$\Rightarrow y=x(4+8)$
Simplify.
$\Rightarrow y=x(12)$
Divide each side by $12$.
$\Rightarrow \frac{y}{12}=\frac{x(12)}{12}$
Simplify.
$\Rightarrow \frac{y}{12}=x$
Hence, the rewritten literal equation is $x= \frac{y}{12}$.
