yx^{2}-z+y\left(-2\right)=xy
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.
yx^{2}-z+y\left(-2\right)-xy=0
Subtract xy from both sides.
yx^{2}+y\left(-2\right)-xy=z
Add z to both sides. Anything plus zero gives itself.
\left(x^{2}-2-x\right)y=z
Combine all terms containing y.
\left(x^{2}-x-2\right)y=z
The equation is in standard form.
\frac{\left(x^{2}-x-2\right)y}{x^{2}-x-2}=\frac{z}{x^{2}-x-2}
Divide both sides by x^{2}-2-x.
y=\frac{z}{x^{2}-x-2}
Dividing by x^{2}-2-x undoes the multiplication by x^{2}-2-x.
y=\frac{z}{\left(x-2\right)\left(x+1\right)}
Divide z by x^{2}-2-x.
y=\frac{z}{\left(x-2\right)\left(x+1\right)}\text{, }y\neq 0
Variable y cannot be equal to 0.
