x+5<0 x-3<0
Kia tōrunga ai te otinga, hei tōraro tahi a x+5 me x-3, hei tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+5 me te x-3.
x<-5
Te otinga e whakaea i ngā koreōrite e rua ko x<-5.
x-3>0 x+5>0
Whakaarohia te tauira ina he tōrunga tahi te x+5 me te x-3.
x>3
Te otinga e whakaea i ngā koreōrite e rua ko x>3.
x<-5\text{; }x>3
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
