\left. \begin{array} { l } { x \neq 0 , y \neq 0 } \\ { \frac { y } { a } - x = 3 x + y = \frac { x } { a } - y } \end{array} \right.
Nilaikan (complex solution)
x\neq 0,\ y\neq 0,\ -x+\frac{y}{a}=3x+y\text{ and }3x+y=-y+\frac{x}{a}
Selesaikan untuk x
\left\{\begin{matrix}x=y\text{, }&y\neq 0\text{ and }a=\frac{1}{5}\\x=-\frac{y}{2}\text{, }&y\neq 0\text{ and }a=-1\end{matrix}\right.
Selesaikan untuk y
\left\{\begin{matrix}y=-2x\text{, }&x\neq 0\text{ and }a=-1\\y=x\text{, }&x\neq 0\text{ and }a=\frac{1}{5}\end{matrix}\right.
