Whakaoti i te x+ay=42

$$x + a y = 42$$

Whakaoti mō a (complex solution)

$$\left\{\begin{matrix}a=-\frac{x-42}{y}\text{, }&y\neq 0\\a\in \mathrm{C}\text{, }&x=42\text{ and }y=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x mai i ngā taha e rua.

$$ay=42-x$$

He hanga arowhānui tō te whārite.

$$ya=42-x$$

Whakawehea ngā taha e rua ki te y.

$$\frac{ya}{y}=\frac{42-x}{y}$$

Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.

$$a=\frac{42-x}{y}$$

Whakaoti mō a

$$\left\{\begin{matrix}a=-\frac{x-42}{y}\text{, }&y\neq 0\\a\in \mathrm{R}\text{, }&x=42\text{ and }y=0\end{matrix}\right.$$
