Kua tāruatia ki te papatopenga
30b+53-18b\geq -83
Tangohia te 18b mai i ngā taha e rua.
12b+53\geq -83
Pahekotia te 30b me -18b, ka 12b.
12b\geq -83-53
Tangohia te 53 mai i ngā taha e rua.
12b\geq -136
Tangohia te 53 i te -83, ka -136.
b\geq \frac{-136}{12}
Whakawehea ngā taha e rua ki te 12. I te mea he tōrunga te 12, kāore e huri te ahunga koreōrite.
b\geq -\frac{34}{3}
Whakahekea te hautanga \frac{-136}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
