Whakaoti i te 18=5.2+(n-1)d

$$18 = 5.2 + ( n - 1 ) d$$

Whakaoti mō d

$$d=\frac{64}{5\left(n-1\right)}$$

$$n\neq 1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te n-1 ki te d.

$$18=5.2+nd-d$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$5.2+nd-d=18$$

Tangohia te 5.2 mai i ngā taha e rua.

$$nd-d=18-5.2$$

Tangohia te 5.2 i te 18, ka 12.8.

$$nd-d=12.8$$

Pahekotia ngā kīanga tau katoa e whai ana i te d.

$$\left(n-1\right)d=12.8$$

He hanga arowhānui tō te whārite.

$$\left(n-1\right)d=\frac{64}{5}$$

Whakawehea ngā taha e rua ki te n-1.

$$\frac{\left(n-1\right)d}{n-1}=\frac{\frac{64}{5}}{n-1}$$

Mā te whakawehe ki te n-1 ka wetekia te whakareanga ki te n-1.

$$d=\frac{\frac{64}{5}}{n-1}$$

Whakawehe \frac{64}{5} ki te n-1.

$$d=\frac{64}{5\left(n-1\right)}$$

Whakaoti mō n

$$n=1+\frac{64}{5d}$$

$$d\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te n-1 ki te d.

$$18=5.2+nd-d$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$5.2+nd-d=18$$

Tangohia te 5.2 mai i ngā taha e rua.

$$nd-d=18-5.2$$

Tangohia te 5.2 i te 18, ka 12.8.

$$nd-d=12.8$$

Me tāpiri te d ki ngā taha e rua.

$$nd=12.8+d$$

He hanga arowhānui tō te whārite.

$$dn=d+\frac{64}{5}$$

Whakawehea ngā taha e rua ki te d.

$$\frac{dn}{d}=\frac{d+\frac{64}{5}}{d}$$

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

$$n=\frac{d+\frac{64}{5}}{d}$$

Whakawehe d+\frac{64}{5} ki te d.

$$n=1+\frac{64}{5d}$$
