Whakaoti i te 9=sqrt{4-9x}

$$9 = \sqrt { 4 - 9 x }$$

Whakaoti mō x

$$x = -\frac{77}{9} = -8\frac{5}{9} \approx -8.555555556$$

Ngā Upane mō te Whakaoti Whārite Pūtake

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

$$\sqrt{4-9x}=9$$

Pūruatia ngā taha e rua o te whārite.

$$-9x+4=81$$

Me tango 4 mai i ngā taha e rua o te whārite.

$$-9x+4-4=81-4$$

Mā te tango i te 4 i a ia ake anō ka toe ko te 0.

$$-9x=81-4$$

Tango 4 mai i 81.

$$-9x=77$$

Whakawehea ngā taha e rua ki te -9.

$$\frac{-9x}{-9}=\frac{77}{-9}$$

Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.

$$x=\frac{77}{-9}$$

Whakawehe 77 ki te -9.

$$x=-\frac{77}{9}$$
