Kua tāruatia ki te papatopenga
9x+8-4x<-x+3
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2-x.
5x+8<-x+3
Pahekotia te 9x me -4x, ka 5x.
5x+8+x<3
Me tāpiri te x ki ngā taha e rua.
6x+8<3
Pahekotia te 5x me x, ka 6x.
6x<3-8
Tangohia te 8 mai i ngā taha e rua.
6x<-5
Tangohia te 8 i te 3, ka -5.
x<-\frac{5}{6}
Whakawehea ngā taha e rua ki te 6. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
