Whakaoti i te 2v-8+4(3v+1)=-2(v+9)

$$2 v - 8 + 4 ( 3 v + 1 ) = - 2 ( v + 9 )$$

Whakaoti mō v

$$v=-\frac{7}{8}=-0.875$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3v+1.

$$2v-8+12v+4=-2\left(v+9\right)$$

Pahekotia te 2v me 12v, ka 14v.

$$14v-8+4=-2\left(v+9\right)$$

Tāpirihia te -8 ki te 4, ka -4.

$$14v-4=-2\left(v+9\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te v+9.

$$14v-4=-2v-18$$

Me tāpiri te 2v ki ngā taha e rua.

$$14v-4+2v=-18$$

Pahekotia te 14v me 2v, ka 16v.

$$16v-4=-18$$

Me tāpiri te 4 ki ngā taha e rua.

$$16v=-18+4$$

Tāpirihia te -18 ki te 4, ka -14.

$$16v=-14$$

Whakawehea ngā taha e rua ki te 16.

$$v=\frac{-14}{16}$$

Whakahekea te hautanga \frac{-14}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$v=-\frac{7}{8}$$
