60+6x-8x\leq 0
Tangohia te 8x mai i ngā taha e rua.
60-2x\leq 0
Pahekotia te 6x me -8x, ka -2x.
-2x\leq -60
Tangohia te 60 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x\geq \frac{-60}{-2}
Whakawehea ngā taha e rua ki te -2. I te mea he tōraro a -2, ka huri te ahunga koreōrite.
x\geq 30
Whakawehea te -60 ki te -2, kia riro ko 30.
