Whakaoti i te 2(1-x)=-2/3

$$2 ( 1 - x ) = - \frac { 2 } { 3 }$$

Whakaoti mō x

$$x = \frac{4}{3} = 1\frac{1}{3} \approx 1.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 2.

$$1-x=\frac{-\frac{2}{3}}{2}$$

Tuhia te \frac{-\frac{2}{3}}{2} hei hautanga kotahi.

$$1-x=\frac{-2}{3\times 2}$$

Whakareatia te 3 ki te 2, ka 6.

$$1-x=\frac{-2}{6}$$

Whakahekea te hautanga \frac{-2}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$1-x=-\frac{1}{3}$$

Tangohia te 1 mai i ngā taha e rua.

$$-x=-\frac{1}{3}-1$$

Me tahuri te 1 ki te hautau \frac{3}{3}.

$$-x=-\frac{1}{3}-\frac{3}{3}$$

Tā te mea he rite te tauraro o -\frac{1}{3} me \frac{3}{3}, me tango rāua mā te tango i ō raua taurunga.

$$-x=\frac{-1-3}{3}$$

Tangohia te 3 i te -1, ka -4.

$$-x=-\frac{4}{3}$$

Me whakarea ngā taha e rua ki te -1.

$$x=\frac{4}{3}$$
