Whakaoti i te 4(2x-7)=10

$$4 ( 2 x - 7 ) = 10$$

Whakaoti mō x

$$x = \frac{19}{4} = 4\frac{3}{4} = 4.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 4.

$$2x-7=\frac{10}{4}$$

Whakahekea te hautanga \frac{10}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$2x-7=\frac{5}{2}$$

Me tāpiri te 7 ki ngā taha e rua.

$$2x=\frac{5}{2}+7$$

Me tahuri te 7 ki te hautau \frac{14}{2}.

$$2x=\frac{5}{2}+\frac{14}{2}$$

Tā te mea he rite te tauraro o \frac{5}{2} me \frac{14}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$2x=\frac{5+14}{2}$$

Tāpirihia te 5 ki te 14, ka 19.

$$2x=\frac{19}{2}$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{\frac{19}{2}}{2}$$

Tuhia te \frac{\frac{19}{2}}{2} hei hautanga kotahi.

$$x=\frac{19}{2\times 2}$$

Whakareatia te 2 ki te 2, ka 4.

$$x=\frac{19}{4}$$
