28mk=300m
The equation is in standard form.
\frac{28mk}{28m}=\frac{300m}{28m}
Divide both sides by 28m.
k=\frac{300m}{28m}
Dividing by 28m undoes the multiplication by 28m.
k=\frac{75}{7}
Divide 300m by 28m.
28km-300m=0
Subtract 300m from both sides.
\left(28k-300\right)m=0
Combine all terms containing m.
m=0
Divide 0 by 28k-300.
