9m+3<9+28m-12-21m
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 7m-3.
9m+3<-3+28m-21m
Tangohia te 12 i te 9, ka -3.
9m+3<-3+7m
Pahekotia te 28m me -21m, ka 7m.
9m+3-7m<-3
Tangohia te 7m mai i ngā taha e rua.
2m+3<-3
Pahekotia te 9m me -7m, ka 2m.
2m<-3-3
Tangohia te 3 mai i ngā taha e rua.
2m<-6
Tangohia te 3 i te -3, ka -6.
m<\frac{-6}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
m<-3
Whakawehea te -6 ki te 2, kia riro ko -3.
