Kua tāruatia ki te papatopenga
-14\leq -x+16
Whakareatia te -2 ki te 7, ka -14.
-x+16\geq -14
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
-x\geq -14-16
Tangohia te 16 mai i ngā taha e rua.
-x\geq -30
Tangohia te 16 i te -14, ka -30.
x\leq \frac{-30}{-1}
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
x\leq 30
Ka taea te hautanga \frac{-30}{-1} te whakamāmā ki te 30 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
