Kua tāruatia ki te papatopenga
-\frac{3}{8}\geq 2+x
Whakawehea ngā taha e rua ki te 8. I te mea he tōrunga te 8, kāore e huri te ahunga koreōrite.
2+x\leq -\frac{3}{8}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
x\leq -\frac{3}{8}-2
Tangohia te 2 mai i ngā taha e rua.
x\leq -\frac{3}{8}-\frac{16}{8}
Me tahuri te 2 ki te hautau \frac{16}{8}.
x\leq \frac{-3-16}{8}
Tā te mea he rite te tauraro o -\frac{3}{8} me \frac{16}{8}, me tango rāua mā te tango i ō raua taurunga.
x\leq -\frac{19}{8}
Tangohia te 16 i te -3, ka -19.
