Whakaoti i te 2(2-n)-2n=-6(1+n)

$$2 ( 2 - n ) - 2 n = - 6 ( 1 + n )$$

Whakaoti mō n

$$n=-5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4-2n-2n=-6\left(1+n\right)$$

Pahekotia te -2n me -2n, ka -4n.

$$4-4n=-6\left(1+n\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te 1+n.

$$4-4n=-6-6n$$

Me tāpiri te 6n ki ngā taha e rua.

$$4-4n+6n=-6$$

Pahekotia te -4n me 6n, ka 2n.

$$4+2n=-6$$

Tangohia te 4 mai i ngā taha e rua.

$$2n=-6-4$$

Tangohia te 4 i te -6, ka -10.

$$2n=-10$$

Whakawehea ngā taha e rua ki te 2.

$$n=\frac{-10}{2}$$

Whakawehea te -10 ki te 2, kia riro ko -5.

$$n=-5$$
