Kua tāruatia ki te papatopenga
800x\leq 144000-1800x
Whakamahia te āhuatanga tohatoha hei whakarea te 1800 ki te 80-x.
800x+1800x\leq 144000
Me tāpiri te 1800x ki ngā taha e rua.
2600x\leq 144000
Pahekotia te 800x me 1800x, ka 2600x.
x\leq \frac{144000}{2600}
Whakawehea ngā taha e rua ki te 2600. I te mea he tōrunga te 2600, kāore e huri te ahunga koreōrite.
x\leq \frac{720}{13}
Whakahekea te hautanga \frac{144000}{2600} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 200.
