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

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

Whakaoti mō x

$$x = -\frac{10}{7} = -1\frac{3}{7} \approx -1.428571429$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x+2.

$$4x+6x+12=-4\left(x+2\right)$$

Pahekotia te 4x me 6x, ka 10x.

$$10x+12=-4\left(x+2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x+2.

$$10x+12=-4x-8$$

Me tāpiri te 4x ki ngā taha e rua.

$$10x+12+4x=-8$$

Pahekotia te 10x me 4x, ka 14x.

$$14x+12=-8$$

Tangohia te 12 mai i ngā taha e rua.

$$14x=-8-12$$

Tangohia te 12 i te -8, ka -20.

$$14x=-20$$

Whakawehea ngā taha e rua ki te 14.

$$x=\frac{-20}{14}$$

Whakahekea te hautanga \frac{-20}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{10}{7}$$
