Kua tāruatia ki te papatopenga
24x-72+7\leq 19
Whakamahia te āhuatanga tohatoha hei whakarea te 24 ki te x-3.
24x-65\leq 19
Tāpirihia te -72 ki te 7, ka -65.
24x\leq 19+65
Me tāpiri te 65 ki ngā taha e rua.
24x\leq 84
Tāpirihia te 19 ki te 65, ka 84.
x\leq \frac{84}{24}
Whakawehea ngā taha e rua ki te 24. I te mea he tōrunga te 24, kāore e huri te ahunga koreōrite.
x\leq \frac{7}{2}
Whakahekea te hautanga \frac{84}{24} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
