Kua tāruatia ki te papatopenga
\frac{-184}{8}\leq 1+4b
Whakawehea ngā taha e rua ki te 8. I te mea he tōrunga te 8, kāore e huri te ahunga koreōrite.
-23\leq 1+4b
Whakawehea te -184 ki te 8, kia riro ko -23.
1+4b\geq -23
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
4b\geq -23-1
Tangohia te 1 mai i ngā taha e rua.
4b\geq -24
Tangohia te 1 i te -23, ka -24.
b\geq \frac{-24}{4}
Whakawehea ngā taha e rua ki te 4. I te mea he tōrunga te 4, kāore e huri te ahunga koreōrite.
b\geq -6
Whakawehea te -24 ki te 4, kia riro ko -6.
