Whakaoti mō x
\left\{\begin{matrix}x\geq \frac{240}{x_{0}+19}\text{, }&x_{0}>-19\\x=\frac{240}{x_{0}+19}\text{, }&x_{0}\neq -19\\x\leq \frac{240}{x_{0}+19}\text{, }&x_{0}<-19\end{matrix}\right.
Whakaoti mō x_0
\left\{\begin{matrix}x_{0}\geq -19+\frac{240}{x}\text{, }&x>0\\x_{0}=-19+\frac{240}{x}\text{, }&x\neq 0\\x_{0}\leq -19+\frac{240}{x}\text{, }&x<0\end{matrix}\right.
