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

$$2 x - ( x + 1 ) = - 2 + 3 ( x - 5 )$$

Whakaoti mō x

$$x=8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o x+1, kimihia te tauaro o ia taurangi.

$$2x-x-1=-2+3\left(x-5\right)$$

Pahekotia te 2x me -x, ka x.

$$x-1=-2+3\left(x-5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-5.

$$x-1=-2+3x-15$$

Tangohia te 15 i te -2, ka -17.

$$x-1=-17+3x$$

Tangohia te 3x mai i ngā taha e rua.

$$x-1-3x=-17$$

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

$$-2x-1=-17$$

Me tāpiri te 1 ki ngā taha e rua.

$$-2x=-17+1$$

Tāpirihia te -17 ki te 1, ka -16.

$$-2x=-16$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-16}{-2}$$

Whakawehea te -16 ki te -2, kia riro ko 8.

$$x=8$$
