Kua tāruatia ki te papatopenga
x+6\geq 0 x+1\leq 0
Kia ≤0 te otinga, me ≥0 rawa tētahi uara o x+6 me x+1, me ≤0 anō te uara o tētahi. Whakaarohia te tauira ina ko x+6\geq 0 me x+1\leq 0.
x\in \begin{bmatrix}-6,-1\end{bmatrix}
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left[-6,-1\right].
x+1\geq 0 x+6\leq 0
Whakaarohia te tauira ina ko x+6\leq 0 me x+1\geq 0.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \begin{bmatrix}-6,-1\end{bmatrix}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
