\frac{2x}{3}+4\geq 0 \frac{1}{3}-x\leq 0
Kia ≤0 te otinga, me ≥0 rawa tētahi uara o \frac{2x}{3}+4 me \frac{1}{3}-x, me ≤0 anō te uara o tētahi. Whakaarohia te tauira ina ko \frac{2x}{3}+4\geq 0 me \frac{1}{3}-x\leq 0.
x\geq \frac{1}{3}
Te otinga e whakaea i ngā koreōrite e rua ko x\geq \frac{1}{3}.
\frac{1}{3}-x\geq 0 \frac{2x}{3}+4\leq 0
Whakaarohia te tauira ina ko \frac{2x}{3}+4\leq 0 me \frac{1}{3}-x\geq 0.
x\leq -6
Te otinga e whakaea i ngā koreōrite e rua ko x\leq -6.
x\geq \frac{1}{3}\text{; }x\leq -6
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
