3\left(x-1\right)-4\left(x-1\right)\geq 24+2\left(1-2x\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3,6. I te mea he tōrunga te 12, kāore e huri te ahunga koreōrite.
3x-3-4\left(x-1\right)\geq 24+2\left(1-2x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
3x-3-4x+4\geq 24+2\left(1-2x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-1.
-x-3+4\geq 24+2\left(1-2x\right)
Pahekotia te 3x me -4x, ka -x.
-x+1\geq 24+2\left(1-2x\right)
Tāpirihia te -3 ki te 4, ka 1.
-x+1\geq 24+2-4x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 1-2x.
-x+1\geq 26-4x
Tāpirihia te 24 ki te 2, ka 26.
-x+1+4x\geq 26
Me tāpiri te 4x ki ngā taha e rua.
3x+1\geq 26
Pahekotia te -x me 4x, ka 3x.
3x\geq 26-1
Tangohia te 1 mai i ngā taha e rua.
3x\geq 25
Tangohia te 1 i te 26, ka 25.
x\geq \frac{25}{3}
Whakawehea ngā taha e rua ki te 3. I te mea he tōrunga te 3, kāore e huri te ahunga koreōrite.
