Solve for x
\left\{\begin{matrix}x=\frac{z}{y-z}\text{, }&y\neq 0\text{ and }z\neq y\\x\neq -1\text{, }&z=0\text{ and }y=0\end{matrix}\right.
Solve for y
\left\{\begin{matrix}y=z+\frac{z}{x}\text{, }&x\neq 0\text{ and }x\neq -1\\y\in \mathrm{R}\text{, }&x=0\text{ and }z=0\end{matrix}\right.

z\left(x+1\right)=xy
Variable x cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by x+1.
zx+z=xy
Use the distributive property to multiply z by x+1.
zx+z-xy=0
Subtract xy from both sides.
zx-xy=-z
Subtract z from both sides. Anything subtracted from zero gives its negation.
\left(z-y\right)x=-z
Combine all terms containing x.
\frac{\left(z-y\right)x}{z-y}=-\frac{z}{z-y}
Divide both sides by z-y.
x=-\frac{z}{z-y}
Dividing by z-y undoes the multiplication by z-y.
x=-\frac{z}{z-y}\text{, }x\neq -1
Variable x cannot be equal to -1.
z\left(x+1\right)=xy
Multiply both sides of the equation by x+1.
zx+z=xy
Use the distributive property to multiply z by x+1.
xy=zx+z
Swap sides so that all variable terms are on the left hand side.
xy=xz+z
The equation is in standard form.
\frac{xy}{x}=\frac{xz+z}{x}
Divide both sides by x.
y=\frac{xz+z}{x}
Dividing by x undoes the multiplication by x.
y=z+\frac{z}{x}
Divide zx+z by x.
