Answer
$y=4-x$
Work Step by Step
The given equation is
$\Rightarrow 10x+5y=5x+20$
Subtract $10x$ from each side.
$\Rightarrow 10x+5y-10x=5x+20-10x$
Simplify.
$\Rightarrow 5y=20-5x$
Divide each side by $5$.
$\Rightarrow \frac{5y}{5}=\frac{20-5x}{5}$
Simplify.
$\Rightarrow y=4-x$
Hence, the rewritten literal equation is $y=4-x$.
