Answer
$y=3-4x$.
Work Step by Step
The given equation is
$\Rightarrow 20x+5y=15$
Subtract $20x$ from each side.
$\Rightarrow 20x+5y-20x=15-20x$
Simplify.
$\Rightarrow 5y=15-20x$
Divide each side by $5$.
$\Rightarrow \frac{5y}{5}=\frac{15-20x}{5}$
Simplify.
$\Rightarrow y=3-4x$
Hence, the rewritten literal equation is $y=3-4x$.
