Kua tāruatia ki te papatopenga
10-2x\geq 6\left(3x-5\right)
Whakareatia ngā taha e rua o te whārite ki te 3. Nō te mea he >0 te 3, ka noho pērā tonu te ahunga koreōrite.
10-2x\geq 18x-30
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 3x-5.
10-2x-18x\geq -30
Tangohia te 18x mai i ngā taha e rua.
10-20x\geq -30
Pahekotia te -2x me -18x, ka -20x.
-20x\geq -30-10
Tangohia te 10 mai i ngā taha e rua.
-20x\geq -40
Tangohia te 10 i te -30, ka -40.
x\leq \frac{-40}{-20}
Whakawehea ngā taha e rua ki te -20. Nō te mea he <0 te -20, ka hurihia te ahunga koreōrite.
x\leq 2
Whakawehea te -40 ki te -20, kia riro ko 2.
