-28x+8960-112x\leq 95
Whakamahia te āhuatanga tohatoha hei whakarea te 112 ki te 80-x.
-140x+8960\leq 95
Pahekotia te -28x me -112x, ka -140x.
-140x\leq 95-8960
Tangohia te 8960 mai i ngā taha e rua.
-140x\leq -8865
Tangohia te 8960 i te 95, ka -8865.
x\geq \frac{-8865}{-140}
Whakawehea ngā taha e rua ki te -140. I te mea he tōraro a -140, ka huri te ahunga koreōrite.
x\geq \frac{1773}{28}
Whakahekea te hautanga \frac{-8865}{-140} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -5.
