Whakaoti i te 3n+6/n-4=2

$$\frac{3n+6}{n-4}=2$$

Whakaoti mō n

$$n=-14$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe n ki 4 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te n-4.

$$3n+6=2\left(n-4\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te n-4.

$$3n+6=2n-8$$

Tangohia te 2n mai i ngā taha e rua.

$$3n+6-2n=-8$$

Pahekotia te 3n me -2n, ka n.

$$n+6=-8$$

Tangohia te 6 mai i ngā taha e rua.

$$n=-8-6$$

Tangohia te 6 i te -8, ka -14.

$$n=-14$$
