-x^{3}+x-a=y

Swap sides so that all variable terms are on the left hand side.

x-a=y+x^{3}

Add x^{3} to both sides.

-a=y+x^{3}-x

Subtract x from both sides.

-a=x^{3}-x+y

The equation is in standard form.

\frac{-a}{-1}=\frac{x^{3}-x+y}{-1}

Divide both sides by -1.

a=\frac{x^{3}-x+y}{-1}

Dividing by -1 undoes the multiplication by -1.

a=-\left(x^{3}-x+y\right)

Divide y+x^{3}-x by -1.
