Whakaoti i te 2-sqrt{v+3}=-7

$$2 - \sqrt { v + 3 } = - 7$$

Whakaoti mō v

$$v=78$$

Ngā Upane mō te Whakaoti Whārite Pūtake

Me tango 2 mai i ngā taha e rua o te whārite.

$$-\sqrt{v+3}+2-2=-7-2$$

Mā te tango i te 2 i a ia ake anō ka toe ko te 0.

$$-\sqrt{v+3}=-7-2$$

Tango 2 mai i -7.

$$-\sqrt{v+3}=-9$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-\sqrt{v+3}}{-1}=-\frac{9}{-1}$$

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

$$\sqrt{v+3}=-\frac{9}{-1}$$

Whakawehe -9 ki te -1.

$$\sqrt{v+3}=9$$

Pūruatia ngā taha e rua o te whārite.

$$v+3=81$$

Me tango 3 mai i ngā taha e rua o te whārite.

$$v+3-3=81-3$$

Mā te tango i te 3 i a ia ake anō ka toe ko te 0.

$$v=81-3$$

Tango 3 mai i 81.

$$v=78$$
