\left\{ \begin{array} { l } { x + y \geq 1 } \\ { x - y \geq - 1 } \\ { 2 x - y \leq 2 } \end{array} \right.
Selesaikan untuk x
x\in \begin{bmatrix}|1-y|,\frac{y+2}{2}\end{bmatrix}\text{, }y\geq 0\text{ and }y\leq 4
Selesaikan untuk y
\left\{\begin{matrix}y\in \begin{bmatrix}1-x,x+1\end{bmatrix}\text{, }&x\geq 0\text{ and }x\leq 1\\y=x+1\text{, }&x=3\\y\in \begin{bmatrix}2\left(x-1\right),x+1\end{bmatrix}\text{, }&x>1\text{ and }x<3\end{matrix}\right.
