Whakaoti i te a*(b-2)=3b

$$a \cdot (b-2) = 3b$$

Whakaoti mō a

$$a=\frac{3b}{b-2}$$

$$b\neq 2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te b-2.

$$ab-2a=3b$$

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

$$\left(b-2\right)a=3b$$

Whakawehea ngā taha e rua ki te b-2.

$$\frac{\left(b-2\right)a}{b-2}=\frac{3b}{b-2}$$

Mā te whakawehe ki te b-2 ka wetekia te whakareanga ki te b-2.

$$a=\frac{3b}{b-2}$$

Whakaoti mō b

$$b=\frac{2a}{a-3}$$

$$a\neq 3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te b-2.

$$ab-2a=3b$$

Tangohia te 3b mai i ngā taha e rua.

$$ab-2a-3b=0$$

Me tāpiri te 2a ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$ab-3b=2a$$

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

$$\left(a-3\right)b=2a$$

Whakawehea ngā taha e rua ki te a-3.

$$\frac{\left(a-3\right)b}{a-3}=\frac{2a}{a-3}$$

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

$$b=\frac{2a}{a-3}$$
