2x+11<0 x-5<0
Kia tōrunga te otinga, me tōraro tahi te 2x+11 me te x-5, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te 2x+11 me te x-5.
x<-\frac{11}{2}
Te otinga e whakaea i ngā koreōrite e rua ko x<-\frac{11}{2}.
x-5>0 2x+11>0
Whakaarohia te tauira ina he tōrunga tahi te 2x+11 me te x-5.
x>5
Te otinga e whakaea i ngā koreōrite e rua ko x>5.
x<-\frac{11}{2}\text{; }x>5
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
