Kua tāruatia ki te papatopenga
3x+3<x+7
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+1.
3x+3-x<7
Tangohia te x mai i ngā taha e rua.
2x+3<7
Pahekotia te 3x me -x, ka 2x.
2x<7-3
Tangohia te 3 mai i ngā taha e rua.
2x<4
Tangohia te 3 i te 7, ka 4.
x<\frac{4}{2}
Whakawehea ngā taha e rua ki te 2. Nō te mea he >0 te 2, ka noho pērā tonu te ahunga koreōrite.
x<2
Whakawehea te 4 ki te 2, kia riro ko 2.
