Whakaoti i te 2/3=9+x/2

$$\frac { 2 } { 3 } = \frac { 9 + x } { 2 }$$

Whakaoti mō x

$$x = -\frac{23}{3} = -7\frac{2}{3} \approx -7.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 2.

$$\frac{2}{3}\times 2=9+x$$

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

$$\frac{2\times 2}{3}=9+x$$

Whakareatia te 2 ki te 2, ka 4.

$$\frac{4}{3}=9+x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$9+x=\frac{4}{3}$$

Tangohia te 9 mai i ngā taha e rua.

$$x=\frac{4}{3}-9$$

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

$$x=\frac{4}{3}-\frac{27}{3}$$

Tā te mea he rite te tauraro o \frac{4}{3} me \frac{27}{3}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{4-27}{3}$$

Tangohia te 27 i te 4, ka -23.

$$x=-\frac{23}{3}$$
