2x+5\leq 3x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
2x+5-3x\leq -6
Tangohia te 3x mai i ngā taha e rua.
-x+5\leq -6
Pahekotia te 2x me -3x, ka -x.
-x\leq -6-5
Tangohia te 5 mai i ngā taha e rua.
-x\leq -11
Tangohia te 5 i te -6, ka -11.
x\geq \frac{-11}{-1}
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
x\geq 11
Ka taea te hautanga \frac{-11}{-1} te whakamāmā ki te 11 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
