200x+160000-1600x<17400
Whakamahia te āhuatanga tohatoha hei whakarea te 1600 ki te 100-x.
-1400x+160000<17400
Pahekotia te 200x me -1600x, ka -1400x.
-1400x<17400-160000
Tangohia te 160000 mai i ngā taha e rua.
-1400x<-142600
Tangohia te 160000 i te 17400, ka -142600.
x>\frac{-142600}{-1400}
Whakawehea ngā taha e rua ki te -1400. I te mea he tōraro a -1400, ka huri te ahunga koreōrite.
x>\frac{713}{7}
Whakahekea te hautanga \frac{-142600}{-1400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -200.
