16-18x+18\geq 3x-8\left(3-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 9x-9.
34-18x\geq 3x-8\left(3-x\right)
Tāpirihia te 16 ki te 18, ka 34.
34-18x\geq 3x-24+8x
Whakamahia te āhuatanga tohatoha hei whakarea te -8 ki te 3-x.
34-18x\geq 11x-24
Pahekotia te 3x me 8x, ka 11x.
34-18x-11x\geq -24
Tangohia te 11x mai i ngā taha e rua.
34-29x\geq -24
Pahekotia te -18x me -11x, ka -29x.
-29x\geq -24-34
Tangohia te 34 mai i ngā taha e rua.
-29x\geq -58
Tangohia te 34 i te -24, ka -58.
x\leq \frac{-58}{-29}
Whakawehea ngā taha e rua ki te -29. Nō te mea he <0 te -29, ka hurihia te ahunga koreōrite.
x\leq 2
Whakawehea te -58 ki te -29, kia riro ko 2.
