1-2x>0 4x+3<0
Kia tōraro ai te otinga, hei tauaro hoki ngā tohu o 1-2x me 4x+3. Whakaarohia te tauira ina he tōrunga te 1-2x he tōraro te 4x+3.
x<-\frac{3}{4}
Te otinga e whakaea i ngā koreōrite e rua ko x<-\frac{3}{4}.
4x+3>0 1-2x<0
Whakaarohia te tauira ina he tōrunga te 4x+3 he tōraro te 1-2x.
x>\frac{1}{2}
Te otinga e whakaea i ngā koreōrite e rua ko x>\frac{1}{2}.
x<-\frac{3}{4}\text{; }x>\frac{1}{2}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
