yx^{2}-y+1=-x
Subtract x from both sides. Anything subtracted from zero gives its negation.
yx^{2}-y=-x-1
Subtract 1 from both sides.
\left(x^{2}-1\right)y=-x-1
Combine all terms containing y.
\frac{\left(x^{2}-1\right)y}{x^{2}-1}=\frac{-x-1}{x^{2}-1}
Divide both sides by x^{2}-1.
y=\frac{-x-1}{x^{2}-1}
Dividing by x^{2}-1 undoes the multiplication by x^{2}-1.
y=-\frac{1}{x-1}
Divide -x-1 by x^{2}-1.
yx^{2}-y+1=-x
Subtract x from both sides. Anything subtracted from zero gives its negation.
yx^{2}-y=-x-1
Subtract 1 from both sides.
