Tohaina
Kua tāruatia ki te papatopenga
225c\leq 20-25
Tangohia te 25 mai i ngā taha e rua.
225c\leq -5
Tangohia te 25 i te 20, ka -5.
c\leq \frac{-5}{225}
Whakawehea ngā taha e rua ki te 225. I te mea he tōrunga te 225, kāore e huri te ahunga koreōrite.
c\leq -\frac{1}{45}
Whakahekea te hautanga \frac{-5}{225} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
