Selesaikan untuk x
\left\{\begin{matrix}x=-\frac{3}{2}=-1.5\text{, }&y\geq \frac{3}{2}\\x\in \begin{bmatrix}\frac{-\sqrt{4y+17}-3}{2},\frac{\sqrt{4y+17}-3}{2}\end{bmatrix}\text{, }&y\geq \sqrt{6}+2\\x=y-3\text{, }&y=2-\sqrt{6}\\x\in \begin{bmatrix}\frac{-\sqrt{4y+17}-3}{2},y-3\end{bmatrix}\text{, }&y>2-\sqrt{6}\text{ and }y<\sqrt{6}+2\end{matrix}\right.
Selesaikan untuk y
