Answer

$x= \frac{m}{9}$.

Work Step by Step

The given equation is $\Rightarrow m=10x-x$ Use distributive property. $\Rightarrow m=x(10-1)$ Simplify. $\Rightarrow m=x(9)$ Divide each side by $9$. $\Rightarrow \frac{m}{9}=\frac{x(9)}{9}$ Simplify. $\Rightarrow \frac{m}{9}=x$ Hence, the rewritten literal equation is $x= \frac{m}{9}$.
