25+125x-99x<51
Tangohia te 99x mai i ngā taha e rua.
25+26x<51
Pahekotia te 125x me -99x, ka 26x.
26x<51-25
Tangohia te 25 mai i ngā taha e rua.
26x<26
Tangohia te 25 i te 51, ka 26.
x<\frac{26}{26}
Whakawehea ngā taha e rua ki te 26. I te mea he tōrunga te 26, kāore e huri te ahunga koreōrite.
x<1
Whakawehea te 26 ki te 26, kia riro ko 1.
