Answer
$x=\frac{m}{2+k}$.
Work Step by Step
The given equation is
$\Rightarrow 2x+kx=m$
Use distributive property.
$\Rightarrow x(2+k)=m$
Divide both sides by $2+k$.
$\Rightarrow \frac{x(2+k)}{2+k}=\frac{m}{2+k}$
Simplify.
$\Rightarrow x=\frac{m}{2+k}$
Hence, the rewritten literal equation is $x=\frac{m}{2+k}$.
