Whakaoti mō P
\left\{\begin{matrix}P=\frac{vz}{x}\text{, }&x\neq 0\\P\in \mathrm{R}\text{, }&\left(v=0\text{ or }z=0\right)\text{ and }x=0\end{matrix}\right.
Whakaoti mō v
\left\{\begin{matrix}v=\frac{Px}{z}\text{, }&z\neq 0\\v\in \mathrm{R}\text{, }&\left(P=0\text{ or }x=0\right)\text{ and }z=0\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
xP=vz
He hanga arowhānui tō te whārite.
\frac{xP}{x}=\frac{vz}{x}
Whakawehea ngā taha e rua ki te x.
P=\frac{vz}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
vz=Px
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
zv=Px
He hanga arowhānui tō te whārite.
\frac{zv}{z}=\frac{Px}{z}
Whakawehea ngā taha e rua ki te z.
v=\frac{Px}{z}
Mā te whakawehe ki te z ka wetekia te whakareanga ki te z.
