Kua tāruatia ki te papatopenga
\frac{1}{2}x-\frac{1}{2}<x
Whakawehea ia wā o x-1 ki te 2, kia riro ko \frac{1}{2}x-\frac{1}{2}.
\frac{1}{2}x-\frac{1}{2}-x<0
Tangohia te x mai i ngā taha e rua.
-\frac{1}{2}x-\frac{1}{2}<0
Pahekotia te \frac{1}{2}x me -x, ka -\frac{1}{2}x.
-\frac{1}{2}x<\frac{1}{2}
Me tāpiri te \frac{1}{2} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x>\frac{1}{2}\left(-2\right)
Me whakarea ngā taha e rua ki te -2, te tau utu o -\frac{1}{2}. I te mea he tōraro a -\frac{1}{2}, ka huri te ahunga koreōrite.
x>\frac{-2}{2}
Whakareatia te \frac{1}{2} ki te -2, ka \frac{-2}{2}.
x>-1
Whakawehea te -2 ki te 2, kia riro ko -1.
