Whakaoti i te -4(v-2)=-4(v-8)-8v

$$- 4 ( v - 2 ) = - 4 ( v - 8 ) - 8 v$$

Whakaoti mō v

$$v=3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te v-2.

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

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te v-8.

$$-4v+8=-4v+32-8v$$

Pahekotia te -4v me -8v, ka -12v.

$$-4v+8=-12v+32$$

Me tāpiri te 12v ki ngā taha e rua.

$$-4v+8+12v=32$$

Pahekotia te -4v me 12v, ka 8v.

$$8v+8=32$$

Tangohia te 8 mai i ngā taha e rua.

$$8v=32-8$$

Tangohia te 8 i te 32, ka 24.

$$8v=24$$

Whakawehea ngā taha e rua ki te 8.

$$v=\frac{24}{8}$$

Whakawehea te 24 ki te 8, kia riro ko 3.

$$v=3$$
