x+1\geq 3\left(x+3\right)-x
Whakamahia te āhuatanga tohatoha hei whakarea te 1 ki te x+1.
x+1\geq 3x+9-x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+3.
x+1\geq 2x+9
Pahekotia te 3x me -x, ka 2x.
x+1-2x\geq 9
Tangohia te 2x mai i ngā taha e rua.
-x+1\geq 9
Pahekotia te x me -2x, ka -x.
-x\geq 9-1
Tangohia te 1 mai i ngā taha e rua.
-x\geq 8
Tangohia te 1 i te 9, ka 8.
x\leq -8
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
