Whakaoti i te 1-x/x+2<-1

$$\frac { 1 - x } { x + 2 } < - 1$$

Whakaoti mō x

$$x<-2$$

Ngā Upane Otinga

Kāore e taea a te tauraro x+2 te numa kore nā te mea kāore te rituatanga mā te kore e tautuhi. E rua ngā kēhi.

$$x+2>0 x+2<0$$

Whakaarohia te kēhi i ngā wā kei te tōrunga a x+2. Neke atu a 2 ki te taha matau.

$$x>-2$$

Kāore te tōrite tuatahi e whakarerekē te aronga ina e whakarea ana mā x+2 mō x+2>0.

$$1-x<-\left(x+2\right)$$

Whakarea te katoa o te taha matau.

$$1-x<-x-2$$

Neke atu ngā kīanga tau e whai ana i x ki te taha mauī me ētahi atu kupu katoa ki te taha matau.

$$-x+x<-1-2$$

Pahekotia ngā kīanga tau ōrite.

$$0<-3$$

Whakaarohia te herenga x>-2 e tautuhi ana ki runga.

$$x\in \emptyset$$

Tēnā, me whakaarohia te tauira ina e tōraro a x+2. Neke atu a 2 ki te taha matau.

$$x<-2$$

E whakarerekē ana te aronga o te tōrite tuatahi hei ngā wā e whakarea ana a x+2 mō x+2<0.

$$1-x>-\left(x+2\right)$$

Whakarea te katoa o te taha matau.

$$1-x>-x-2$$

Neke atu ngā kīanga tau e whai ana i x ki te taha mauī me ētahi atu kupu katoa ki te taha matau.

$$-x+x>-1-2$$

Pahekotia ngā kīanga tau ōrite.

$$0>-3$$

Whakaarohia te herenga x<-2 e tautuhi ana ki runga.

$$x<-2$$

Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.

$$x<-2$$
