Whakaoti i te 6(4.5x-12)=9

$$6(4.5x-12)=9$$

Whakaoti mō x

$$x=3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 6.

$$4.5x-12=\frac{9}{6}$$

Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$4.5x-12=\frac{3}{2}$$

Me tāpiri te 12 ki ngā taha e rua.

$$4.5x=\frac{3}{2}+12$$

Me tahuri te 12 ki te hautau \frac{24}{2}.

$$4.5x=\frac{3}{2}+\frac{24}{2}$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{24}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$4.5x=\frac{3+24}{2}$$

Tāpirihia te 3 ki te 24, ka 27.

$$4.5x=\frac{27}{2}$$

Whakawehea ngā taha e rua ki te 4.5.

$$x=\frac{\frac{27}{2}}{4.5}$$

Tuhia te \frac{\frac{27}{2}}{4.5} hei hautanga kotahi.

$$x=\frac{27}{2\times 4.5}$$

Whakareatia te 2 ki te 4.5, ka 9.

$$x=\frac{27}{9}$$

Whakawehea te 27 ki te 9, kia riro ko 3.

$$x=3$$
