2x+4\leq 0 5-x<0
Kia ≥0 rawa te otinga, hei ≤0 a 2x+4 me 5-x tahi, hei ≥0 rānei rāua tahi, otiia tē taea ai hei kore te 5-x. Whakaarohia te tauira ina tōraro tahi a 2x+4\leq 0 me 5-x.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
2x+4\geq 0 5-x>0
Whakaarohia te tauira ina tōrunga tahi a 2x+4\geq 0 me 5-x.
x\in [-2,5)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left[-2,5\right).
x\in [-2,5)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
