x+4\leq 0 x-3<0
Kia ≥0 rawa te otinga, hei ≤0 a x+4 me x-3 tahi, hei ≥0 rānei rāua tahi, otiia tē taea ai hei kore te x-3. Whakaarohia te tauira ina tōraro tahi a x+4\leq 0 me x-3.
x\leq -4
Te otinga e whakaea i ngā koreōrite e rua ko x\leq -4.
x+4\geq 0 x-3>0
Whakaarohia te tauira ina tōrunga tahi a x+4\geq 0 me x-3.
x>3
Te otinga e whakaea i ngā koreōrite e rua ko x>3.
x\leq -4\text{; }x>3
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
