Whakaoti i te -19n+8n=-(n+18)-14(n-5)

$$- 19 n + 8 n = - ( n + 18 ) - 14 ( n - 5 )$$

Whakaoti mō n

$$n=13$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te -19n me 8n, ka -11n.

$$-11n=-\left(n+18\right)-14\left(n-5\right)$$

Hei kimi i te tauaro o n+18, kimihia te tauaro o ia taurangi.

$$-11n=-n-18-14\left(n-5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -14 ki te n-5.

$$-11n=-n-18-14n+70$$

Pahekotia te -n me -14n, ka -15n.

$$-11n=-15n-18+70$$

Tāpirihia te -18 ki te 70, ka 52.

$$-11n=-15n+52$$

Me tāpiri te 15n ki ngā taha e rua.

$$-11n+15n=52$$

Pahekotia te -11n me 15n, ka 4n.

$$4n=52$$

Whakawehea ngā taha e rua ki te 4.

$$n=\frac{52}{4}$$

Whakawehea te 52 ki te 4, kia riro ko 13.

$$n=13$$
