3x+1>0 4x-2<0
Kia tōraro ai te otinga, hei tauaro hoki ngā tohu o 3x+1 me 4x-2. Whakaarohia te tauira ina he tōrunga te 3x+1 he tōraro te 4x-2.
x\in \left(-\frac{1}{3},\frac{1}{2}\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-\frac{1}{3},\frac{1}{2}\right).
4x-2>0 3x+1<0
Whakaarohia te tauira ina he tōrunga te 4x-2 he tōraro te 3x+1.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \left(-\frac{1}{3},\frac{1}{2}\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
