Whakaoti i te p=w_{2}-v_{2}

$$p = w _ { 2 } - v _ { 2 }$$

Whakaoti mō v_2

$$v_{2}=w_{2}-p$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$w_{2}-v_{2}=p$$

Tangohia te w_{2} mai i ngā taha e rua.

$$-v_{2}=p-w_{2}$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-v_{2}}{-1}=\frac{p-w_{2}}{-1}$$

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

$$v_{2}=\frac{p-w_{2}}{-1}$$

Whakawehe p-w_{2} ki te -1.

$$v_{2}=w_{2}-p$$

Whakaoti mō p

$$p=w_{2}-v_{2}$$
