Tohaina
Kua tāruatia ki te papatopenga
-15c\leq 10-43
Tangohia te 43 mai i ngā taha e rua.
-15c\leq -33
Tangohia te 43 i te 10, ka -33.
c\geq \frac{-33}{-15}
Whakawehea ngā taha e rua ki te -15. I te mea he tōraro a -15, ka huri te ahunga koreōrite.
c\geq \frac{11}{5}
Whakahekea te hautanga \frac{-33}{-15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.
