\frac{1}{4}x+3-\frac{2}{3}x<-2
Tangohia te \frac{2}{3}x mai i ngā taha e rua.
-\frac{5}{12}x+3<-2
Pahekotia te \frac{1}{4}x me -\frac{2}{3}x, ka -\frac{5}{12}x.
-\frac{5}{12}x<-2-3
Tangohia te 3 mai i ngā taha e rua.
-\frac{5}{12}x<-5
Tangohia te 3 i te -2, ka -5.
x>-5\left(-\frac{12}{5}\right)
Me whakarea ngā taha e rua ki te -\frac{12}{5}, te tau utu o -\frac{5}{12}. I te mea he tōraro a -\frac{5}{12}, ka huri te ahunga koreōrite.
x>12
Whakareatia -5 ki te -\frac{12}{5}.
