Whakaoti i te 2=4a+b

$$2 = 4 a + b$$

Whakaoti mō a

$$a=-\frac{b}{4}+\frac{1}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4a+b=2$$

Tangohia te b mai i ngā taha e rua.

$$4a=2-b$$

Whakawehea ngā taha e rua ki te 4.

$$\frac{4a}{4}=\frac{2-b}{4}$$

Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.

$$a=\frac{2-b}{4}$$

Whakawehe 2-b ki te 4.

$$a=-\frac{b}{4}+\frac{1}{2}$$

Whakaoti mō b

$$b=2-4a$$

Ngā Upane Otinga

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

$$4a+b=2$$

Tangohia te 4a mai i ngā taha e rua.

$$b=2-4a$$
