\frac{1}{2}x+3-2x<-6
Tangohia te 2x mai i ngā taha e rua.
-\frac{3}{2}x+3<-6
Pahekotia te \frac{1}{2}x me -2x, ka -\frac{3}{2}x.
-\frac{3}{2}x<-6-3
Tangohia te 3 mai i ngā taha e rua.
-\frac{3}{2}x<-9
Tangohia te 3 i te -6, ka -9.
x>-9\left(-\frac{2}{3}\right)
Me whakarea ngā taha e rua ki te -\frac{2}{3}, te tau utu o -\frac{3}{2}. I te mea he tōraro a -\frac{3}{2}, ka huri te ahunga koreōrite.
x>\frac{-9\left(-2\right)}{3}
Tuhia te -9\left(-\frac{2}{3}\right) hei hautanga kotahi.
x>\frac{18}{3}
Whakareatia te -9 ki te -2, ka 18.
x>6
Whakawehea te 18 ki te 3, kia riro ko 6.
