fx=-k
Subtract k from both sides. Anything subtracted from zero gives its negation.
xf=-k
The equation is in standard form.
\frac{xf}{x}=-\frac{k}{x}
Divide both sides by x.
f=-\frac{k}{x}
Dividing by x undoes the multiplication by x.
fx=-k
Subtract k from both sides. Anything subtracted from zero gives its negation.
xf=-k

\frac{xf}{x}=-\frac{k}{x}
Divide both sides by x.
f=-\frac{k}{x}
