Whakaoti i te 6x+(-x-2)=(7x-3)-(8-x)

$$6 x + ( - x - 2 ) = ( 7 x - 3 ) - ( 8 - x )$$

Whakaoti mō x

$$x=3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o 8-x, kimihia te tauaro o ia taurangi.

$$6x-x-2=7x-3-8-\left(-x\right)$$

Ko te tauaro o -x ko x.

$$6x-x-2=7x-3-8+x$$

Tangohia te 8 i te -3, ka -11.

$$6x-x-2=7x-11+x$$

Pahekotia te 7x me x, ka 8x.

$$6x-x-2=8x-11$$

Tangohia te 8x mai i ngā taha e rua.

$$6x-x-2-8x=-11$$

Pahekotia te 6x me -8x, ka -2x.

$$-2x-x-2=-11$$

Me tāpiri te 2 ki ngā taha e rua.

$$-2x-x=-11+2$$

Tāpirihia te -11 ki te 2, ka -9.

$$-2x-x=-9$$

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

$$-3x=-9$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{-9}{-3}$$

Whakawehea te -9 ki te -3, kia riro ko 3.

$$x=3$$
