x+20-2x\geq 30
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 10-x.
-x+20\geq 30
Pahekotia te x me -2x, ka -x.
-x\geq 30-20
Tangohia te 20 mai i ngā taha e rua.
-x\geq 10
Tangohia te 20 i te 30, ka 10.
x\leq -10
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
