Tohaina
Kua tāruatia ki te papatopenga
-2x+10-x\geq -8
Tangohia te x mai i ngā taha e rua.
-3x+10\geq -8
Pahekotia te -2x me -x, ka -3x.
-3x\geq -8-10
Tangohia te 10 mai i ngā taha e rua.
-3x\geq -18
Tangohia te 10 i te -8, ka -18.
x\leq \frac{-18}{-3}
Whakawehea ngā taha e rua ki te -3. I te mea he tōraro a -3, ka huri te ahunga koreōrite.
x\leq 6
Whakawehea te -18 ki te -3, kia riro ko 6.
