Kua tāruatia ki te papatopenga
88x+2700-45x\leq 4000
Whakamahia te āhuatanga tohatoha hei whakarea te 45 ki te 60-x.
43x+2700\leq 4000
Pahekotia te 88x me -45x, ka 43x.
43x\leq 4000-2700
Tangohia te 2700 mai i ngā taha e rua.
43x\leq 1300
Tangohia te 2700 i te 4000, ka 1300.
x\leq \frac{1300}{43}
Whakawehea ngā taha e rua ki te 43. I te mea he tōrunga te 43, kāore e huri te ahunga koreōrite.
