Kua tāruatia ki te papatopenga
3x-27-25x\leq 0
Tangohia te 25x mai i ngā taha e rua.
-22x-27\leq 0
Pahekotia te 3x me -25x, ka -22x.
-22x\leq 27
Me tāpiri te 27 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x\geq -\frac{27}{22}
Whakawehea ngā taha e rua ki te -22. I te mea he tōraro a -22, ka huri te ahunga koreōrite.
