Whakaoti i te 3(2w+4)=10

$$3 ( 2 w + 4 ) = 10$$

Whakaoti mō w

$$w=-\frac{1}{3}\approx -0.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 3.

$$2w+4=\frac{10}{3}$$

Tangohia te 4 mai i ngā taha e rua.

$$2w=\frac{10}{3}-4$$

Me tahuri te 4 ki te hautau \frac{12}{3}.

$$2w=\frac{10}{3}-\frac{12}{3}$$

Tā te mea he rite te tauraro o \frac{10}{3} me \frac{12}{3}, me tango rāua mā te tango i ō raua taurunga.

$$2w=\frac{10-12}{3}$$

Tangohia te 12 i te 10, ka -2.

$$2w=-\frac{2}{3}$$

Whakawehea ngā taha e rua ki te 2.

$$w=\frac{-\frac{2}{3}}{2}$$

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

$$w=\frac{-2}{3\times 2}$$

Whakareatia te 3 ki te 2, ka 6.

$$w=\frac{-2}{6}$$

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

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