Whakaoti i te H=2/3(7+M)d

$$H = \frac { 2 } { 3 } ( 7 + M ) d$$

Whakaoti mō H

$$H=\frac{2d\left(M+7\right)}{3}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{2}{3} ki te 7+M.

$$H=\left(\frac{14}{3}+\frac{2}{3}M\right)d$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{14}{3}+\frac{2}{3}M ki te d.

$$H=\frac{14}{3}d+\frac{2}{3}Md$$

Whakaoti mō M

$$\left\{\begin{matrix}M=\frac{3H}{2d}-7\text{, }&d\neq 0\\M\in \mathrm{R}\text{, }&H=0\text{ and }d=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{2}{3} ki te 7+M.

$$H=\left(\frac{14}{3}+\frac{2}{3}M\right)d$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{14}{3}+\frac{2}{3}M ki te d.

$$H=\frac{14}{3}d+\frac{2}{3}Md$$

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

$$\frac{14}{3}d+\frac{2}{3}Md=H$$

Tangohia te \frac{14}{3}d mai i ngā taha e rua.

$$\frac{2}{3}Md=H-\frac{14}{3}d$$

He hanga arowhānui tō te whārite.

$$\frac{2d}{3}M=-\frac{14d}{3}+H$$

Whakawehea ngā taha e rua ki te \frac{2}{3}d.

$$\frac{3\times \frac{2d}{3}M}{2d}=\frac{3\left(-\frac{14d}{3}+H\right)}{2d}$$

Mā te whakawehe ki te \frac{2}{3}d ka wetekia te whakareanga ki te \frac{2}{3}d.

$$M=\frac{3\left(-\frac{14d}{3}+H\right)}{2d}$$

Whakawehe H-\frac{14d}{3} ki te \frac{2}{3}d.

$$M=\frac{3H}{2d}-7$$
