Kua tāruatia ki te papatopenga
4x+40-55x\leq 0
Tangohia te 55x mai i ngā taha e rua.
-51x+40\leq 0
Pahekotia te 4x me -55x, ka -51x.
-51x\leq -40
Tangohia te 40 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x\geq \frac{-40}{-51}
Whakawehea ngā taha e rua ki te -51. I te mea he tōraro a -51, ka huri te ahunga koreōrite.
x\geq \frac{40}{51}
Ka taea te hautanga \frac{-40}{-51} te whakamāmā ki te \frac{40}{51} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
