Kua tāruatia ki te papatopenga
2.5x+2400\geq 80000
Tāpirihia te -600 ki te 3000, ka 2400.
2.5x\geq 80000-2400
Tangohia te 2400 mai i ngā taha e rua.
2.5x\geq 77600
Tangohia te 2400 i te 80000, ka 77600.
x\geq \frac{77600}{2.5}
Whakawehea ngā taha e rua ki te 2.5. I te mea he tōrunga te 2.5, kāore e huri te ahunga koreōrite.
x\geq \frac{776000}{25}
Whakarohaina te \frac{77600}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x\geq 31040
Whakawehea te 776000 ki te 25, kia riro ko 31040.
