2x+1<0 x-3<0
Kia tōrunga ai te otinga, hei tōraro tahi a 2x+1 me x-3, hei tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te 2x+1 me te x-3.
x<-\frac{1}{2}
Te otinga e whakaea i ngā koreōrite e rua ko x<-\frac{1}{2}.
x-3>0 2x+1>0
Whakaarohia te tauira ina he tōrunga tahi te 2x+1 me te x-3.
x>3
Te otinga e whakaea i ngā koreōrite e rua ko x>3.
x<-\frac{1}{2}\text{; }x>3
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
