3x-2<0 x+5<0
Kia tōrunga ai te otinga, hei tōraro tahi a 3x-2 me x+5, hei tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te 3x-2 me te x+5.
x<-5
Te otinga e whakaea i ngā koreōrite e rua ko x<-5.
x+5>0 3x-2>0
Whakaarohia te tauira ina he tōrunga tahi te 3x-2 me te x+5.
x>\frac{2}{3}
Te otinga e whakaea i ngā koreōrite e rua ko x>\frac{2}{3}.
x<-5\text{; }x>\frac{2}{3}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
