Tohaina
Kua tāruatia ki te papatopenga
14<-16j-48-2
Whakamahia te āhuatanga tohatoha hei whakarea te -16 ki te j+3.
14<-16j-50
Tangohia te 2 i te -48, ka -50.
-16j-50>14
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
-16j>14+50
Me tāpiri te 50 ki ngā taha e rua.
-16j>64
Tāpirihia te 14 ki te 50, ka 64.
j<\frac{64}{-16}
Whakawehea ngā taha e rua ki te -16. I te mea he tōraro a -16, ka huri te ahunga koreōrite.
j<-4
Whakawehea te 64 ki te -16, kia riro ko -4.
