24-2\left(x-1\right)\geq 3\left(x+2\right)
Me whakarea ngā taha e rua o te whārite ki te 8, arā, te tauraro pātahi he tino iti rawa te kitea o 4,8. I te mea he tōrunga te 8, kāore e huri te ahunga koreōrite.
24-2x+2\geq 3\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.
26-2x\geq 3\left(x+2\right)
Tāpirihia te 24 ki te 2, ka 26.
26-2x\geq 3x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+2.
26-2x-3x\geq 6
Tangohia te 3x mai i ngā taha e rua.
26-5x\geq 6
Pahekotia te -2x me -3x, ka -5x.
-5x\geq 6-26
Tangohia te 26 mai i ngā taha e rua.
-5x\geq -20
Tangohia te 26 i te 6, ka -20.
x\leq \frac{-20}{-5}
Whakawehea ngā taha e rua ki te -5. I te mea he tōraro a -5, ka huri te ahunga koreōrite.
x\leq 4
Whakawehea te -20 ki te -5, kia riro ko 4.
