Whakaoti i te -2(v+2)+7=3(v+6)

$$- 2 ( v + 2 ) + 7 = 3 ( v + 6 )$$

Whakaoti mō v

$$v=-3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te v+2.

$$-2v-4+7=3\left(v+6\right)$$

Tāpirihia te -4 ki te 7, ka 3.

$$-2v+3=3\left(v+6\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te v+6.

$$-2v+3=3v+18$$

Tangohia te 3v mai i ngā taha e rua.

$$-2v+3-3v=18$$

Pahekotia te -2v me -3v, ka -5v.

$$-5v+3=18$$

Tangohia te 3 mai i ngā taha e rua.

$$-5v=18-3$$

Tangohia te 3 i te 18, ka 15.

$$-5v=15$$

Whakawehea ngā taha e rua ki te -5.

$$v=\frac{15}{-5}$$

Whakawehea te 15 ki te -5, kia riro ko -3.

$$v=-3$$
