x+4<0 x+2<0
Kia tōrunga te otinga, me tōraro tahi te x+4 me te x+2, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+4 me te x+2.
x<-4
Te otinga e whakaea i ngā koreōrite e rua ko x<-4.
x+2>0 x+4>0
Whakaarohia te tauira ina he tōrunga tahi te x+4 me te x+2.
x>-2
Te otinga e whakaea i ngā koreōrite e rua ko x>-2.
x<-4\text{; }x>-2
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
