\frac{14m}{5}k=300m
The equation is in standard form.
\frac{5\times \frac{14m}{5}k}{14m}=\frac{5\times 300m}{14m}
Divide both sides by 2.8m.
k=\frac{5\times 300m}{14m}
Dividing by 2.8m undoes the multiplication by 2.8m.
k=\frac{750}{7}
Divide 300m by 2.8m.
2.8km-300m=0
Subtract 300m from both sides.
\left(2.8k-300\right)m=0
Combine all terms containing m.
\left(\frac{14k}{5}-300\right)m=0
The equation is in standard form.
m=0
Divide 0 by -300+2.8k.
