Whakaoti i te 12x+2[6+7(x+1)]=0

$$12 x + 2 [ 6 + 7 ( x + 1 ) ] = 0$$

Whakaoti mō x

$$x=-1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x+1.

$$12x+2\left(6+7x+7\right)=0$$

Tāpirihia te 6 ki te 7, ka 13.

$$12x+2\left(13+7x\right)=0$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 13+7x.

$$12x+26+14x=0$$

Pahekotia te 12x me 14x, ka 26x.

$$26x+26=0$$

Tangohia te 26 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$26x=-26$$

Whakawehea ngā taha e rua ki te 26.

$$x=\frac{-26}{26}$$

Whakawehea te -26 ki te 26, kia riro ko -1.

$$x=-1$$
