Ngā Upane mō te Whakaoti Whārite Rārangi

Tāpirihia te 9 ki te 5, ka 14.

$$14-2x=3\times 2x+3\times 4$$

Whakareatia te 3 ki te 2, ka 6. Whakareatia te 3 ki te 4, ka 12.

$$14-2x=6x+12$$

Tangohia te 6x mai i ngā taha e rua.

$$14-2x-6x=12$$

Pahekotia te -2x me -6x, ka -8x.

$$14-8x=12$$

Tangohia te 14 mai i ngā taha e rua.

$$-8x=12-14$$

Tangohia te 14 i te 12, ka -2.

$$-8x=-2$$

Whakawehea ngā taha e rua ki te -8.

$$x=\frac{-2}{-8}$$

Whakahekea te hautanga \frac{-2}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.

$$x=\frac{1}{4}$$
