xf=8x-x^{2}
The equation is in standard form.
\frac{xf}{x}=\frac{x\left(8-x\right)}{x}
Divide both sides by x.
f=\frac{x\left(8-x\right)}{x}
Dividing by x undoes the multiplication by x.
f=8-x
Divide x\left(8-x\right) by x.
xf=8x-x^{2}
The equation is in standard form.
\frac{xf}{x}=\frac{x\left(8-x\right)}{x}
Divide both sides by x.
f=\frac{x\left(8-x\right)}{x}
Dividing by x undoes the multiplication by x.
f=8-x
Divide x\left(8-x\right) by x.
