km=643m
Swap sides so that all variable terms are on the left hand side.
mk=643m
The equation is in standard form.
\frac{mk}{m}=\frac{643m}{m}
Divide both sides by m.
k=\frac{643m}{m}
Dividing by m undoes the multiplication by m.
k=643
Divide 643m by m.
643m-km=0
Subtract km from both sides.
\left(643-k\right)m=0
Combine all terms containing m.
m=0
Divide 0 by 643-k.
