Kua tāruatia ki te papatopenga
-9x\leq -2
Pahekotia te -3x me -6x, ka -9x.
x\geq \frac{-2}{-9}
Whakawehea ngā taha e rua ki te -9. I te mea he tōraro a -9, ka huri te ahunga koreōrite.
x\geq \frac{2}{9}
Ka taea te hautanga \frac{-2}{-9} te whakamāmā ki te \frac{2}{9} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
