Answer

$y=x-3$.

Work Step by Step

The given equation is $\Rightarrow 4x-5=7+4y$ Subtract $7$ from each side. $\Rightarrow 4x-5-7=7+4y-7$ Simplify. $\Rightarrow 4x-12=4y$ Divide both sides by $4$. $\Rightarrow \frac{4x-12}{4}=\frac{4y}{4}$ Simplify. $\Rightarrow x-3=y$ Hence, the rewritten literal equation is $y=x-3$.
