Kua tāruatia ki te papatopenga
2x-3+4x\times 2\geq 4
Whakareatia ngā taha e rua o te whārite ki te 4. I te mea he tōrunga te 4, kāore e huri te ahunga koreōrite.
2x-3+8x\geq 4
Whakareatia te 4 ki te 2, ka 8.
10x-3\geq 4
Pahekotia te 2x me 8x, ka 10x.
10x\geq 4+3
Me tāpiri te 3 ki ngā taha e rua.
10x\geq 7
Tāpirihia te 4 ki te 3, ka 7.
x\geq \frac{7}{10}
Whakawehea ngā taha e rua ki te 10. I te mea he tōrunga te 10, kāore e huri te ahunga koreōrite.
