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