Whakaoti i te 6(45x-12)=9

$$6(45x-12)=9$$

Whakaoti mō x

$$x=\frac{3}{10}=0.3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 6.

$$45x-12=\frac{9}{6}$$

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

$$45x-12=\frac{3}{2}$$

Me tāpiri te 12 ki ngā taha e rua.

$$45x=\frac{3}{2}+12$$

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

$$45x=\frac{3}{2}+\frac{24}{2}$$

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.

$$45x=\frac{3+24}{2}$$

Tāpirihia te 3 ki te 24, ka 27.

$$45x=\frac{27}{2}$$

Whakawehea ngā taha e rua ki te 45.

$$x=\frac{\frac{27}{2}}{45}$$

Tuhia te \frac{\frac{27}{2}}{45} hei hautanga kotahi.

$$x=\frac{27}{2\times 45}$$

Whakareatia te 2 ki te 45, ka 90.

$$x=\frac{27}{90}$$

Whakahekea te hautanga \frac{27}{90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$x=\frac{3}{10}$$
