Kua tāruatia ki te papatopenga
18\geq 42+5x
Whakareatia ngā taha e rua o te whārite ki te 6. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
42+5x\leq 18
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
5x\leq 18-42
Tangohia te 42 mai i ngā taha e rua.
5x\leq -24
Tangohia te 42 i te 18, ka -24.
x\leq -\frac{24}{5}
Whakawehea ngā taha e rua ki te 5. I te mea he tōrunga te 5, kāore e huri te ahunga koreōrite.
