2-x\leq 0 3x+12<0
Kia ≥0 rawa te otinga, hei ≤0 a 2-x me 3x+12 tahi, hei ≥0 rānei rāua tahi, otiia tē taea ai hei kore te 3x+12. Whakaarohia te tauira ina tōraro tahi a 2-x\leq 0 me 3x+12.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
2-x\geq 0 3x+12>0
Whakaarohia te tauira ina tōrunga tahi a 2-x\geq 0 me 3x+12.
x\in (-4,2]
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-4,2\right].
x\in (-4,2]
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
