Whakaoti i te y=h(x+2)

$$y = h ( x + 2 )$$

Whakaoti mō h

$$\left\{\begin{matrix}h=\frac{y}{x+2}\text{, }&x\neq -2\\h\in \mathrm{R}\text{, }&y=0\text{ and }x=-2\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te h ki te x+2.

$$y=hx+2h$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$hx+2h=y$$

Pahekotia ngā kīanga tau katoa e whai ana i te h.

$$\left(x+2\right)h=y$$

Whakawehea ngā taha e rua ki te x+2.

$$\frac{\left(x+2\right)h}{x+2}=\frac{y}{x+2}$$

Mā te whakawehe ki te x+2 ka wetekia te whakareanga ki te x+2.

$$h=\frac{y}{x+2}$$

Whakaoti mō x

$$\left\{\begin{matrix}x=\frac{y}{h}-2\text{, }&h\neq 0\\x\in \mathrm{R}\text{, }&y=0\text{ and }h=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te h ki te x+2.

$$y=hx+2h$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$hx+2h=y$$

Tangohia te 2h mai i ngā taha e rua.

$$hx=y-2h$$

Whakawehea ngā taha e rua ki te h.

$$\frac{hx}{h}=\frac{y-2h}{h}$$

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

$$x=\frac{y-2h}{h}$$

Whakawehe y-2h ki te h.

$$x=\frac{y}{h}-2$$
