-x-2<0 3x+3<0
Kia tōrunga te otinga, me tōraro tahi te -x-2 me te 3x+3, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te -x-2 me te 3x+3.
x\in \left(-2,-1\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-2,-1\right).
3x+3>0 -x-2>0
Whakaarohia te tauira ina he tōrunga tahi te -x-2 me te 3x+3.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \left(-2,-1\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
