Kua tāruatia ki te papatopenga
x+14\leq -12x+21
Whakamahia te āhuatanga tohatoha hei whakarea te 4x-7 ki te -3.
x+14+12x\leq 21
Me tāpiri te 12x ki ngā taha e rua.
13x+14\leq 21
Pahekotia te x me 12x, ka 13x.
13x\leq 21-14
Tangohia te 14 mai i ngā taha e rua.
13x\leq 7
Tangohia te 14 i te 21, ka 7.
x\leq \frac{7}{13}
Whakawehea ngā taha e rua ki te 13. I te mea he tōrunga te 13, kāore e huri te ahunga koreōrite.
