Tohaina
Kua tāruatia ki te papatopenga
u+5\geq \frac{-2}{-1}
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
u+5\geq 2
Ka taea te hautanga \frac{-2}{-1} te whakamāmā ki te 2 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
u\geq 2-5
Tangohia te 5 mai i ngā taha e rua.
u\geq -3
Tangohia te 5 i te 2, ka -3.
