Whakaoti i te 2n-2(x+4)=5x+6

$$2 n - 2 ( x + 4 ) = 5 x + 6$$

Whakaoti mō n

$$n=\frac{7\left(x+2\right)}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2n-2x-8=5x+6$$

Me tāpiri te 2x ki ngā taha e rua.

$$2n-8=5x+6+2x$$

Pahekotia te 5x me 2x, ka 7x.

$$2n-8=7x+6$$

Me tāpiri te 8 ki ngā taha e rua.

$$2n=7x+6+8$$

Tāpirihia te 6 ki te 8, ka 14.

$$2n=7x+14$$

Whakawehea ngā taha e rua ki te 2.

$$\frac{2n}{2}=\frac{7x+14}{2}$$

Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.

$$n=\frac{7x+14}{2}$$

Whakawehe 14+7x ki te 2.

$$n=\frac{7x}{2}+7$$

Whakaoti mō x

$$x=\frac{2\left(n-7\right)}{7}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2n-2x-8=5x+6$$

Tangohia te 5x mai i ngā taha e rua.

$$2n-2x-8-5x=6$$

Pahekotia te -2x me -5x, ka -7x.

$$2n-7x-8=6$$

Tangohia te 2n mai i ngā taha e rua.

$$-7x-8=6-2n$$

Me tāpiri te 8 ki ngā taha e rua.

$$-7x=6-2n+8$$

Tāpirihia te 6 ki te 8, ka 14.

$$-7x=14-2n$$

Whakawehea ngā taha e rua ki te -7.

$$\frac{-7x}{-7}=\frac{14-2n}{-7}$$

Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.

$$x=\frac{14-2n}{-7}$$

Whakawehe 14-2n ki te -7.

$$x=\frac{2n}{7}-2$$
