Whakaoti i te (N-2)*(P*1.20)-576=0

$$( N - 2 ) \times ( P \times 1.20 ) - 576 = 0$$

Whakaoti mō N

$$N=2+\frac{480}{P}$$

$$P\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te N-2 ki te P.

$$\left(NP-2P\right)\times 1.2-576=0$$

Whakamahia te āhuatanga tohatoha hei whakarea te NP-2P ki te 1.2.

$$1.2NP-2.4P-576=0$$

Me tāpiri te 2.4P ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$1.2NP-576=2.4P$$

Me tāpiri te 576 ki ngā taha e rua.

$$1.2NP=2.4P+576$$

He hanga arowhānui tō te whārite.

$$\frac{6P}{5}N=\frac{12P}{5}+576$$

Whakawehea ngā taha e rua ki te 1.2P.

$$\frac{5\times \frac{6P}{5}N}{6P}=\frac{5\left(\frac{12P}{5}+576\right)}{6P}$$

Mā te whakawehe ki te 1.2P ka wetekia te whakareanga ki te 1.2P.

$$N=\frac{5\left(\frac{12P}{5}+576\right)}{6P}$$

Whakawehe \frac{12P}{5}+576 ki te 1.2P.

$$N=2+\frac{480}{P}$$

Whakaoti mō P

$$P=\frac{480}{N-2}$$

$$N\neq 2$$

$$1.2NP-2.4P-576=0$$

Me tāpiri te 576 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$1.2NP-2.4P=576$$

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

$$\left(1.2N-2.4\right)P=576$$

He hanga arowhānui tō te whārite.

$$\frac{6N-12}{5}P=576$$

Whakawehea ngā taha e rua ki te 1.2N-2.4.

$$\frac{5\times \frac{6N-12}{5}P}{6N-12}=\frac{5\times 576}{6N-12}$$

Mā te whakawehe ki te 1.2N-2.4 ka wetekia te whakareanga ki te 1.2N-2.4.

$$P=\frac{5\times 576}{6N-12}$$

Whakawehe 576 ki te 1.2N-2.4.

$$P=\frac{2880}{6N-12}$$
