Kua tāruatia ki te papatopenga
-\frac{5}{2}\times 8\geq v
Me whakarea ngā taha e rua ki te 8. I te mea he tōrunga te 8, kāore e huri te ahunga koreōrite.
\frac{-5\times 8}{2}\geq v
Tuhia te -\frac{5}{2}\times 8 hei hautanga kotahi.
\frac{-40}{2}\geq v
Whakareatia te -5 ki te 8, ka -40.
-20\geq v
Whakawehea te -40 ki te 2, kia riro ko -20.
v\leq -20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
