90m+6000-120m\leq 480
Whakamahia te āhuatanga tohatoha hei whakarea te 120 ki te 50-m.
-30m+6000\leq 480
Pahekotia te 90m me -120m, ka -30m.
-30m\leq 480-6000
Tangohia te 6000 mai i ngā taha e rua.
-30m\leq -5520
Tangohia te 6000 i te 480, ka -5520.
m\geq \frac{-5520}{-30}
Whakawehea ngā taha e rua ki te -30. I te mea he tōraro a -30, ka huri te ahunga koreōrite.
m\geq 184
Whakawehea te -5520 ki te -30, kia riro ko 184.
