Kua tāruatia ki te papatopenga
6x+10x\geq 120-15x
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,3,2. I te mea he tōrunga te 30, kāore e huri te ahunga koreōrite.
16x\geq 120-15x
Pahekotia te 6x me 10x, ka 16x.
16x+15x\geq 120
Me tāpiri te 15x ki ngā taha e rua.
31x\geq 120
Pahekotia te 16x me 15x, ka 31x.
x\geq \frac{120}{31}
Whakawehea ngā taha e rua ki te 31. I te mea he tōrunga te 31, kāore e huri te ahunga koreōrite.
