Kua tāruatia ki te papatopenga
4x+1+5x\geq 3
Me tāpiri te 5x ki ngā taha e rua.
9x+1\geq 3
Pahekotia te 4x me 5x, ka 9x.
9x\geq 3-1
Tangohia te 1 mai i ngā taha e rua.
9x\geq 2
Tangohia te 1 i te 3, ka 2.
x\geq \frac{2}{9}
Whakawehea ngā taha e rua ki te 9. I te mea he tōrunga te 9, kāore e huri te ahunga koreōrite.
