rx=y
Swap sides so that all variable terms are on the left hand side.
xr=y
The equation is in standard form.
\frac{xr}{x}=\frac{y}{x}
Divide both sides by x.
r=\frac{y}{x}
Dividing by x undoes the multiplication by x.
rx=y
Swap sides so that all variable terms are on the left hand side.
\frac{rx}{r}=\frac{y}{r}
Divide both sides by r.
x=\frac{y}{r}
Dividing by r undoes the multiplication by r.
