xk=81.2
Swap sides so that all variable terms are on the left hand side.
\frac{xk}{x}=\frac{81.2}{x}
Divide both sides by x.
k=\frac{81.2}{x}
Dividing by x undoes the multiplication by x.
k=\frac{406}{5x}
Divide 81.2 by x.
xk=81.2
Swap sides so that all variable terms are on the left hand side.
kx=81.2
The equation is in standard form.
\frac{kx}{k}=\frac{81.2}{k}
Divide both sides by k.
x=\frac{81.2}{k}
Dividing by k undoes the multiplication by k.
x=\frac{406}{5k}
Divide 81.2 by k.
