140x\geq 12600-600
Tangohia te 600 mai i ngā taha e rua.
140x\geq 12000
Tangohia te 600 i te 12600, ka 12000.
x\geq \frac{12000}{140}
Whakawehea ngā taha e rua ki te 140. I te mea he tōrunga te 140, kāore e huri te ahunga koreōrite.
x\geq \frac{600}{7}
Whakahekea te hautanga \frac{12000}{140} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
