-kx+x+8=-2x^{2}
Subtract 2x^{2} from both sides. Anything subtracted from zero gives its negation.
-kx+8=-2x^{2}-x
Subtract x from both sides.
-kx=-2x^{2}-x-8
Subtract 8 from both sides.
\left(-x\right)k=-2x^{2}-x-8
The equation is in standard form.
\frac{\left(-x\right)k}{-x}=\frac{-2x^{2}-x-8}{-x}
Divide both sides by -x.
k=\frac{-2x^{2}-x-8}{-x}
Dividing by -x undoes the multiplication by -x.
k=2x+1+\frac{8}{x}
Divide -2x^{2}-x-8 by -x.
