x+2<0 3-x<0
Kia tōrunga te otinga, me tōraro tahi te x+2 me te 3-x, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+2 me te 3-x.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
3-x>0 x+2>0
Whakaarohia te tauira ina he tōrunga tahi te x+2 me te 3-x.
x\in \left(-2,3\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-2,3\right).
x\in \left(-2,3\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
