-efrx=1
Reorder the terms.
\left(-erx\right)f=1
The equation is in standard form.
\frac{\left(-erx\right)f}{-erx}=\frac{1}{-erx}
Divide both sides by -erx.
f=\frac{1}{-erx}
Dividing by -erx undoes the multiplication by -erx.
f=-\frac{1}{erx}
Divide 1 by -erx.
-efrx=1
Reorder the terms.
\left(-efx\right)r=1
The equation is in standard form.
\frac{\left(-efx\right)r}{-efx}=\frac{1}{-efx}
Divide both sides by -efx.
r=\frac{1}{-efx}
Dividing by -efx undoes the multiplication by -efx.
r=-\frac{1}{efx}
Divide 1 by -efx.
