Kua tāruatia ki te papatopenga
x+5\geq 0 x+1\leq 0
Kia ≤0 te otinga, me ≥0 rawa tētahi uara o x+5 me x+1, me ≤0 anō te uara o tētahi. Whakaarohia te tauira ina ko x+5\geq 0 me x+1\leq 0.
x\in \begin{bmatrix}-5,-1\end{bmatrix}
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left[-5,-1\right].
x+1\geq 0 x+5\leq 0
Whakaarohia te tauira ina ko x+5\leq 0 me x+1\geq 0.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \begin{bmatrix}-5,-1\end{bmatrix}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
