Réitigh RPhi=p*100/T*ST

$$R \Phi = \frac { p \times 100 } { T \times S T }$$

Réitigh do R.

$$\left\{\begin{matrix}R=\frac{100p}{S\Phi T^{2}}\text{, }&T\neq 0\text{ and }S\neq 0\text{ and }\Phi \neq 0\\R\in \mathrm{R}\text{, }&p=0\text{ and }\Phi =0\text{ and }T\neq 0\text{ and }S\neq 0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh an dá thaobh den chothromóid faoi ST^{2}.

$$R\Phi ST^{2}=p\times 100$$

Athordaigh na téarmaí.

$$RS\Phi T^{2}=100p$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$S\Phi T^{2}R=100p$$

Roinn an dá thaobh faoi S\Phi T^{2}.

$$\frac{S\Phi T^{2}R}{S\Phi T^{2}}=\frac{100p}{S\Phi T^{2}}$$

Má roinntear é faoi S\Phi T^{2} cuirtear an iolrúchán faoi S\Phi T^{2} ar ceal.

$$R=\frac{100p}{S\Phi T^{2}}$$

Réitigh do S.

$$\left\{\begin{matrix}S=\frac{100p}{R\Phi T^{2}}\text{, }&p\neq 0\text{ and }T\neq 0\text{ and }\Phi \neq 0\text{ and }R\neq 0\\S\neq 0\text{, }&\left(\Phi =0\text{ or }R=0\right)\text{ and }p=0\text{ and }T\neq 0\end{matrix}\right.$$
