Kua tāruatia ki te papatopenga
\frac{-21}{3}>x
Whakawehea ngā taha e rua ki te 3. I te mea he tōrunga te 3, kāore e huri te ahunga koreōrite.
-7>x
Whakawehea te -21 ki te 3, kia riro ko -7.
x<-7
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
