4-x<0 x-2<0
Kia tōrunga ai te otinga, hei tōraro tahi a 4-x me x-2, hei tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te 4-x me te x-2.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x-2>0 4-x>0
Whakaarohia te tauira ina he tōrunga tahi te 4-x me te x-2.
x\in \left(2,4\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(2,4\right).
x\in \left(2,4\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
