1-x\leq 0 3-x<0
Kia ≥0 rawa te otinga, hei ≤0 a 1-x me 3-x tahi, hei ≥0 rānei rāua tahi, otiia tē taea ai hei kore te 3-x. Whakaarohia te tauira ina tōraro tahi a 1-x\leq 0 me 3-x.
x>3
Te otinga e whakaea i ngā koreōrite e rua ko x>3.
1-x\geq 0 3-x>0
Whakaarohia te tauira ina tōrunga tahi a 1-x\geq 0 me 3-x.
x\leq 1
Te otinga e whakaea i ngā koreōrite e rua ko x\leq 1.
x>3\text{; }x\leq 1
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
