Whakaoti i te 8(x+7)+8=-6(x-4)-2

$$8 ( x + 7 ) + 8 = - 6 ( x - 4 ) - 2$$

Whakaoti mō x

$$x=-3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+7.

$$8x+56+8=-6\left(x-4\right)-2$$

Tāpirihia te 56 ki te 8, ka 64.

$$8x+64=-6\left(x-4\right)-2$$

Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-4.

$$8x+64=-6x+24-2$$

Tangohia te 2 i te 24, ka 22.

$$8x+64=-6x+22$$

Me tāpiri te 6x ki ngā taha e rua.

$$8x+64+6x=22$$

Pahekotia te 8x me 6x, ka 14x.

$$14x+64=22$$

Tangohia te 64 mai i ngā taha e rua.

$$14x=22-64$$

Tangohia te 64 i te 22, ka -42.

$$14x=-42$$

Whakawehea ngā taha e rua ki te 14.

$$x=\frac{-42}{14}$$

Whakawehea te -42 ki te 14, kia riro ko -3.

$$x=-3$$
