2-5x>0 4-x<0
Kia tōraro te otinga, me tauaro rawa ngā tohu o te 2-5x me te 4-x. Whakaarohia te tauira ina he tōrunga te 2-5x he tōraro te 4-x.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
4-x>0 2-5x<0
Whakaarohia te tauira ina he tōrunga te 4-x he tōraro te 2-5x.
x\in \left(\frac{2}{5},4\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(\frac{2}{5},4\right).
x\in \left(\frac{2}{5},4\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
