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