AUB-A=0
Subtract A from both sides.
\left(UB-1\right)A=0
Combine all terms containing A.
\left(BU-1\right)A=0
The equation is in standard form.
A=0
Divide 0 by UB-1.
AUB=A
The equation is in standard form.
\frac{AUB}{AU}=\frac{A}{AU}
Divide both sides by AU.
B=\frac{A}{AU}
Dividing by AU undoes the multiplication by AU.
B=\frac{1}{U}
Divide A by AU.
AUB-A=0
Subtract A from both sides.
\left(UB-1\right)A=0
