Kua tāruatia ki te papatopenga
7x+5-x\geq -2
Tangohia te x mai i ngā taha e rua.
6x+5\geq -2
Pahekotia te 7x me -x, ka 6x.
6x\geq -2-5
Tangohia te 5 mai i ngā taha e rua.
6x\geq -7
Tangohia te 5 i te -2, ka -7.
x\geq -\frac{7}{6}
Whakawehea ngā taha e rua ki te 6. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
