14x+11-12x\geq -3
Tangohia te 12x mai i ngā taha e rua.
2x+11\geq -3
Pahekotia te 14x me -12x, ka 2x.
2x\geq -3-11
Tangohia te 11 mai i ngā taha e rua.
2x\geq -14
Tangohia te 11 i te -3, ka -14.
x\geq \frac{-14}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
x\geq -7
Whakawehea te -14 ki te 2, kia riro ko -7.
