Whakaoti i te 4x+8(8)+2(-1)+6(3)=-2

$$4x+8(8)+2(-1)+6(3)=-2$$

Whakaoti mō x

$$x = -\frac{41}{2} = -20\frac{1}{2} = -20.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 8 ki te 8, ka 64. Whakareatia te 2 ki te -1, ka -2. Whakareatia te 6 ki te 3, ka 18.

$$4x+64-2+18=-2$$

Tangohia te 2 i te 64, ka 62.

$$4x+62+18=-2$$

Tāpirihia te 62 ki te 18, ka 80.

$$4x+80=-2$$

Tangohia te 80 mai i ngā taha e rua.

$$4x=-2-80$$

Tangohia te 80 i te -2, ka -82.

$$4x=-82$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{-82}{4}$$

Whakahekea te hautanga \frac{-82}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{41}{2}$$
