Whakaoti i te 2(x-1)-(x-4)=3(x+8)

$$2 ( x - 1 ) - ( x - 4 ) = 3 ( x + 8 )$$

Whakaoti mō x

$$x=-11$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2x-2-\left(x-4\right)=3\left(x+8\right)$$

Hei kimi i te tauaro o x-4, kimihia te tauaro o ia taurangi.

$$2x-2-x-\left(-4\right)=3\left(x+8\right)$$

Ko te tauaro o -4 ko 4.

$$2x-2-x+4=3\left(x+8\right)$$

Pahekotia te 2x me -x, ka x.

$$x-2+4=3\left(x+8\right)$$

Tāpirihia te -2 ki te 4, ka 2.

$$x+2=3\left(x+8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+8.

$$x+2=3x+24$$

Tangohia te 3x mai i ngā taha e rua.

$$x+2-3x=24$$

Pahekotia te x me -3x, ka -2x.

$$-2x+2=24$$

Tangohia te 2 mai i ngā taha e rua.

$$-2x=24-2$$

Tangohia te 2 i te 24, ka 22.

$$-2x=22$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{22}{-2}$$

Whakawehea te 22 ki te -2, kia riro ko -11.

$$x=-11$$
