Kua tāruatia ki te papatopenga
-18>15a+45-3
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te a+3.
-18>15a+42
Tangohia te 3 i te 45, ka 42.
15a+42<-18
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
15a<-18-42
Tangohia te 42 mai i ngā taha e rua.
15a<-60
Tangohia te 42 i te -18, ka -60.
a<\frac{-60}{15}
Whakawehea ngā taha e rua ki te 15. Nō te mea he >0 te 15, ka noho pērā tonu te ahunga koreōrite.
a<-4
Whakawehea te -60 ki te 15, kia riro ko -4.
