Work Step by Step

We are trying to isolate $x$ in the equation $S=C+xC$ To do this, first we factor out the $C$ using the distributive property: $S=C(1+x)$ Next, we divide both sides of the equation by $C$ to remove it from the right side: $\frac{S}{C}=1+x$ Finally, we subtract $1$ from each side to isolate $x$: $\frac{S}{C}-1=x$
