Kua tāruatia ki te papatopenga
-67b+6-9b\leq 43
Tangohia te 9b mai i ngā taha e rua.
-76b+6\leq 43
Pahekotia te -67b me -9b, ka -76b.
-76b\leq 43-6
Tangohia te 6 mai i ngā taha e rua.
-76b\leq 37
Tangohia te 6 i te 43, ka 37.
b\geq -\frac{37}{76}
Whakawehea ngā taha e rua ki te -76. I te mea he tōraro a -76, ka huri te ahunga koreōrite.
