Kua tāruatia ki te papatopenga
6x-1\geq 2x-10+1
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-5.
6x-1\geq 2x-9
Tāpirihia te -10 ki te 1, ka -9.
6x-1-2x\geq -9
Tangohia te 2x mai i ngā taha e rua.
4x-1\geq -9
Pahekotia te 6x me -2x, ka 4x.
4x\geq -9+1
Me tāpiri te 1 ki ngā taha e rua.
4x\geq -8
Tāpirihia te -9 ki te 1, ka -8.
x\geq \frac{-8}{4}
Whakawehea ngā taha e rua ki te 4. I te mea he tōrunga te 4, kāore e huri te ahunga koreōrite.
x\geq -2
Whakawehea te -8 ki te 4, kia riro ko -2.
