Answer
$x=\frac{a}{2+6z}$, where $z\neq0$.
Work Step by Step
The given equation is
$\Rightarrow a=2x+6xz$
Use distributive property.
$\Rightarrow a=x(2+6z)$
Divide each side by $2+6z$.
$\Rightarrow \frac{a}{2+6z}=\frac{x(2+6z)}{2+6z}$
Simplify.
$\Rightarrow \frac{a}{2+6z}=x$
Hence, the rewritten literal equation is $x=\frac{a}{2+6z}$, where $z\neq0$.
