Whakaoti i te sqrt{3x+40}-17=-12

$$\sqrt { 3 x + 40 } - 17 = - 12$$

Whakaoti mō x

$$x=-5$$

Ngā Upane mō te Whakaoti Whārite Pūtake

Me tāpiri 17 ki ngā taha e rua o te whārite.

$$\sqrt{3x+40}-17-\left(-17\right)=-12-\left(-17\right)$$

Mā te tango i te -17 i a ia ake anō ka toe ko te 0.

$$\sqrt{3x+40}=-12-\left(-17\right)$$

Tango -17 mai i -12.

$$\sqrt{3x+40}=5$$

Pūruatia ngā taha e rua o te whārite.

$$3x+40=25$$

Me tango 40 mai i ngā taha e rua o te whārite.

$$3x+40-40=25-40$$

Mā te tango i te 40 i a ia ake anō ka toe ko te 0.

$$3x=25-40$$

Tango 40 mai i 25.

$$3x=-15$$

Whakawehea ngā taha e rua ki te 3.

$$\frac{3x}{3}=-\frac{15}{3}$$

Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.

$$x=-\frac{15}{3}$$

Whakawehe -15 ki te 3.

$$x=-5$$
