ar_{1}=a-ae
Use the distributive property to multiply a by 1-e.
ar_{1}-a=-ae
Subtract a from both sides.
ar_{1}-a+ae=0
Add ae to both sides.
\left(r_{1}-1+e\right)a=0
Combine all terms containing a.
\left(r_{1}+e-1\right)a=0
The equation is in standard form.
a=0
Divide 0 by r_{1}-1+e.
ar_{1}=a-ae
Use the distributive property to multiply a by 1-e.
ar_{1}=a-ea
The equation is in standard form.
\frac{ar_{1}}{a}=\frac{a-ea}{a}
Divide both sides by a.
r_{1}=\frac{a-ea}{a}
Dividing by a undoes the multiplication by a.
r_{1}=1-e
Divide a-ae by a.
