Solve for x
\left\{\begin{matrix}x\in \begin{bmatrix}y-2,-\frac{y}{3}\end{bmatrix}\text{, }&y\geq 1\text{ and }y\leq \frac{3}{2}\\x=-\frac{y}{3}\text{, }&y=0\\x\in \begin{bmatrix}-y,-\frac{y}{3}\end{bmatrix}\text{, }&y>0\text{ and }y<1\end{matrix}\right.
Solve for y
\left\{\begin{matrix}y\in \begin{bmatrix}-x,-3x\end{bmatrix}\text{, }&x\geq -\frac{1}{2}\text{ and }x\leq 0\\y\in \begin{bmatrix}-x,x+2\end{bmatrix}\text{, }&x\geq -1\text{ and }x<-\frac{1}{2}\end{matrix}\right.
