Whakaoti i te a=2b(c-d)

$$a = 2 b ( c - d )$$

Whakaoti mō b

$$\left\{\begin{matrix}b=\frac{a}{2\left(c-d\right)}\text{, }&c\neq d\\b\in \mathrm{R}\text{, }&a=0\text{ and }c=d\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2b ki te c-d.

$$a=2bc-2db$$

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

$$2bc-2db=a$$

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

$$\left(2c-2d\right)b=a$$

Whakawehea ngā taha e rua ki te 2c-2d.

$$\frac{\left(2c-2d\right)b}{2c-2d}=\frac{a}{2c-2d}$$

Mā te whakawehe ki te 2c-2d ka wetekia te whakareanga ki te 2c-2d.

$$b=\frac{a}{2c-2d}$$

Whakawehe a ki te 2c-2d.

$$b=\frac{a}{2\left(c-d\right)}$$

Whakaoti mō a

$$a=2b\left(c-d\right)$$
