x\geq 0 5x+10<0
Kia ≤0 rawa te otinga, hei ≥0 tonu tētahi o ngā uara o x me 5x+10, hei ≤0 anō tērā atu, otiia tē taea ai hei kore te 5x+10. Whakaarohia te tauira ina tōraro tahi a x\geq 0 me 5x+10.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\leq 0 5x+10>0
Whakaarohia te tauira ina tōrunga tahi a x\leq 0 me 5x+10.
x\in (-2,0]
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-2,0\right].
x\in (-2,0]
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
