3x-6\geq x-4
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
3x-6-x\geq -4
Tangohia te x mai i ngā taha e rua.
2x-6\geq -4
Pahekotia te 3x me -x, ka 2x.
2x\geq -4+6
Me tāpiri te 6 ki ngā taha e rua.
2x\geq 2
Tāpirihia te -4 ki te 6, ka 2.
x\geq \frac{2}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
x\geq 1
Whakawehea te 2 ki te 2, kia riro ko 1.
