rn=-1
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
\frac{rn}{r}=-\frac{1}{r}
Divide both sides by r.
n=-\frac{1}{r}
Dividing by r undoes the multiplication by r.
rn=-1
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
nr=-1
The equation is in standard form.
\frac{nr}{n}=-\frac{1}{n}
Divide both sides by n.
r=-\frac{1}{n}
Dividing by n undoes the multiplication by n.
