Whakaoti i te (N-2)*(P*120)-576=0

$$( N - 2 ) \times ( P \times 120 ) - 576 = 0$$

Whakaoti mō N

$$N=2+\frac{24}{5P}$$

$$P\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\left(NP-2P\right)\times 120-576=0$$

Whakamahia te āhuatanga tohatoha hei whakarea te NP-2P ki te 120.

$$120NP-240P-576=0$$

Me tāpiri te 240P ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$120NP-576=240P$$

Me tāpiri te 576 ki ngā taha e rua.

$$120NP=240P+576$$

He hanga arowhānui tō te whārite.

$$120PN=240P+576$$

Whakawehea ngā taha e rua ki te 120P.

$$\frac{120PN}{120P}=\frac{240P+576}{120P}$$

Mā te whakawehe ki te 120P ka wetekia te whakareanga ki te 120P.

$$N=\frac{240P+576}{120P}$$

Whakawehe 240P+576 ki te 120P.

$$N=2+\frac{24}{5P}$$

Whakaoti mō P

$$P=\frac{24}{5\left(N-2\right)}$$

$$N\neq 2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\left(NP-2P\right)\times 120-576=0$$

Whakamahia te āhuatanga tohatoha hei whakarea te NP-2P ki te 120.

$$120NP-240P-576=0$$

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

$$120NP-240P=576$$

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

$$\left(120N-240\right)P=576$$

Whakawehea ngā taha e rua ki te 120N-240.

$$\frac{\left(120N-240\right)P}{120N-240}=\frac{576}{120N-240}$$

Mā te whakawehe ki te 120N-240 ka wetekia te whakareanga ki te 120N-240.

$$P=\frac{576}{120N-240}$$

Whakawehe 576 ki te 120N-240.

$$P=\frac{24}{5\left(N-2\right)}$$
