Whakaoti i te r=(b-3)m

$$r = ( b - 3 ) m$$

Whakaoti mō b

$$\left\{\begin{matrix}b=\frac{r}{m}+3\text{, }&m\neq 0\\b\in \mathrm{R}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te b-3 ki te m.

$$r=bm-3m$$

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

$$bm-3m=r$$

Me tāpiri te 3m ki ngā taha e rua.

$$bm=r+3m$$

He hanga arowhānui tō te whārite.

$$mb=3m+r$$

Whakawehea ngā taha e rua ki te m.

$$\frac{mb}{m}=\frac{3m+r}{m}$$

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

$$b=\frac{3m+r}{m}$$

Whakawehe r+3m ki te m.

$$b=\frac{r}{m}+3$$

Whakaoti mō m

$$\left\{\begin{matrix}m=-\frac{r}{3-b}\text{, }&b\neq 3\\m\in \mathrm{R}\text{, }&r=0\text{ and }b=3\end{matrix}\right.$$

Whakamahia te āhuatanga tohatoha hei whakarea te b-3 ki te m.

$$r=bm-3m$$

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

$$bm-3m=r$$

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

$$\left(b-3\right)m=r$$

Whakawehea ngā taha e rua ki te b-3.

$$\frac{\left(b-3\right)m}{b-3}=\frac{r}{b-3}$$

Mā te whakawehe ki te b-3 ka wetekia te whakareanga ki te b-3.

$$m=\frac{r}{b-3}$$
