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

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

Whakaoti mō x

$$x = -\frac{19}{5} = -3\frac{4}{5} = -3.8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

Tāpirihia te -4 ki te 6, ka 2.

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

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+4.

$$-2x+2=8x+32+8$$

Tāpirihia te 32 ki te 8, ka 40.

$$-2x+2=8x+40$$

Tangohia te 8x mai i ngā taha e rua.

$$-2x+2-8x=40$$

Pahekotia te -2x me -8x, ka -10x.

$$-10x+2=40$$

Tangohia te 2 mai i ngā taha e rua.

$$-10x=40-2$$

Tangohia te 2 i te 40, ka 38.

$$-10x=38$$

Whakawehea ngā taha e rua ki te -10.

$$x=\frac{38}{-10}$$

Whakahekea te hautanga \frac{38}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{19}{5}$$
