Whakaoti i te -9(2y-3)=1

$$- 9 ( 2 y - 3 ) = 1$$

Whakaoti mō y

$$y = \frac{13}{9} = 1\frac{4}{9} \approx 1.444444444$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te -9.

$$2y-3=-\frac{1}{9}$$

Me tāpiri te 3 ki ngā taha e rua.

$$2y=-\frac{1}{9}+3$$

Me tahuri te 3 ki te hautau \frac{27}{9}.

$$2y=-\frac{1}{9}+\frac{27}{9}$$

Tā te mea he rite te tauraro o -\frac{1}{9} me \frac{27}{9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$2y=\frac{-1+27}{9}$$

Tāpirihia te -1 ki te 27, ka 26.

$$2y=\frac{26}{9}$$

Whakawehea ngā taha e rua ki te 2.

$$y=\frac{\frac{26}{9}}{2}$$

Tuhia te \frac{\frac{26}{9}}{2} hei hautanga kotahi.

$$y=\frac{26}{9\times 2}$$

Whakareatia te 9 ki te 2, ka 18.

$$y=\frac{26}{18}$$

Whakahekea te hautanga \frac{26}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$y=\frac{13}{9}$$
