2\left(2x-1\right)-6\geq 6x-3\left(5-3x\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
4x-2-6\geq 6x-3\left(5-3x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-1.
4x-8\geq 6x-3\left(5-3x\right)
Tangohia te 6 i te -2, ka -8.
4x-8\geq 6x-15+9x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 5-3x.
4x-8\geq 15x-15
Pahekotia te 6x me 9x, ka 15x.
4x-8-15x\geq -15
Tangohia te 15x mai i ngā taha e rua.
-11x-8\geq -15
Pahekotia te 4x me -15x, ka -11x.
-11x\geq -15+8
Me tāpiri te 8 ki ngā taha e rua.
-11x\geq -7
Tāpirihia te -15 ki te 8, ka -7.
x\leq \frac{-7}{-11}
Whakawehea ngā taha e rua ki te -11. I te mea he tōraro a -11, ka huri te ahunga koreōrite.
x\leq \frac{7}{11}
Ka taea te hautanga \frac{-7}{-11} te whakamāmā ki te \frac{7}{11} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
