Kua tāruatia ki te papatopenga
12x\leq 25-71
Tangohia te 71 mai i ngā taha e rua.
12x\leq -46
Tangohia te 71 i te 25, ka -46.
x\leq \frac{-46}{12}
Whakawehea ngā taha e rua ki te 12. I te mea he tōrunga te 12, kāore e huri te ahunga koreōrite.
x\leq -\frac{23}{6}
Whakahekea te hautanga \frac{-46}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
