Whakaoti i te x-y=a-b

$$x - y = a - b$$

Whakaoti mō a

$$a=x-y+b$$

Ngā Upane Otinga

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

$$a-b=x-y$$

Me tāpiri te b ki ngā taha e rua.

$$a=x-y+b$$

Whakaoti mō b

$$b=a+y-x$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$a-b=x-y$$

Tangohia te a mai i ngā taha e rua.

$$-b=x-y-a$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-b}{-1}=\frac{x-y-a}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$b=\frac{x-y-a}{-1}$$

Whakawehe x-y-a ki te -1.

$$b=a+y-x$$
