-fx=5-1
Subtract 1 from both sides.
-fx=4
Subtract 1 from 5 to get 4.
\left(-x\right)f=4
The equation is in standard form.
\frac{\left(-x\right)f}{-x}=\frac{4}{-x}
Divide both sides by -x.
f=\frac{4}{-x}
Dividing by -x undoes the multiplication by -x.
f=-\frac{4}{x}
Divide 4 by -x.
-fx=5-1
Subtract 1 from both sides.
-fx=4
Subtract 1 from 5 to get 4.
\left(-f\right)x=4
The equation is in standard form.
\frac{\left(-f\right)x}{-f}=\frac{4}{-f}
Divide both sides by -f.
x=\frac{4}{-f}
Dividing by -f undoes the multiplication by -f.
x=-\frac{4}{f}
Divide 4 by -f.
