Kua tāruatia ki te papatopenga
-19j<-20j-95+20j
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te -4j-19.
-19j<-95
Pahekotia te -20j me 20j, ka 0.
j>\frac{-95}{-19}
Whakawehea ngā taha e rua ki te -19. I te mea he tōraro a -19, ka huri te ahunga koreōrite.
j>5
Whakawehea te -95 ki te -19, kia riro ko 5.
