Kua tāruatia ki te papatopenga
-\frac{1}{4}x>21-5
Tangohia te 5 mai i ngā taha e rua.
-\frac{1}{4}x>16
Tangohia te 5 i te 21, ka 16.
x<16\left(-4\right)
Me whakarea ngā taha e rua ki te -4, te tau utu o -\frac{1}{4}. I te mea he tōraro a -\frac{1}{4}, ka huri te ahunga koreōrite.
x<-64
Whakareatia te 16 ki te -4, ka -64.
