Kua tāruatia ki te papatopenga
12x>9-151
Tangohia te 151 mai i ngā taha e rua.
12x>-142
Tangohia te 151 i te 9, ka -142.
x>\frac{-142}{12}
Whakawehea ngā taha e rua ki te 12. Nō te mea he >0 te 12, ka noho pērā tonu te ahunga koreōrite.
x>-\frac{71}{6}
Whakahekea te hautanga \frac{-142}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
