Whakaoti i te 2(3x-2)-5x+7leq2(x+1)

$$2 ( 3 x - 2 ) - 5 x + 7 \leq 2 ( x + 1 )$$

Whakaoti mō x

$$x\geq 1$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x-2.

$$6x-4-5x+7\leq 2\left(x+1\right)$$

Pahekotia te 6x me -5x, ka x.

$$x-4+7\leq 2\left(x+1\right)$$

Tāpirihia te -4 ki te 7, ka 3.

$$x+3\leq 2\left(x+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.

$$x+3\leq 2x+2$$

Tangohia te 2x mai i ngā taha e rua.

$$x+3-2x\leq 2$$

Pahekotia te x me -2x, ka -x.

$$-x+3\leq 2$$

Tangohia te 3 mai i ngā taha e rua.

$$-x\leq 2-3$$

Tangohia te 3 i te 2, ka -1.

$$-x\leq -1$$

Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.

$$x\geq \frac{-1}{-1}$$

Whakawehea te -1 ki te -1, kia riro ko 1.

$$x\geq 1$$
