2kx=-20
Subtract 20 from both sides. Anything subtracted from zero gives its negation.
2xk=-20
The equation is in standard form.
\frac{2xk}{2x}=-\frac{20}{2x}
Divide both sides by 2x.
k=-\frac{20}{2x}
Dividing by 2x undoes the multiplication by 2x.
k=-\frac{10}{x}
Divide -20 by 2x.
2kx=-20
Subtract 20 from both sides. Anything subtracted from zero gives its negation.
\frac{2kx}{2k}=-\frac{20}{2k}
Divide both sides by 2k.
x=-\frac{20}{2k}
Dividing by 2k undoes the multiplication by 2k.
x=-\frac{10}{k}
Divide -20 by 2k.
