Réitigh n/R_{200}=a+bT+cT

$$\frac { n } { R _ { 200 } } = a + b T + c T$$

Réitigh do R_200.

$$\left\{\begin{matrix}R_{200}=\frac{n}{Tb+Tc+a}\text{, }&n\neq 0\text{ and }a\neq -T\left(b+c\right)\\R_{200}\neq 0\text{, }&a=-T\left(b+c\right)\text{ and }n=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Ní féidir leis an athróg R_{200} a bheith comhionann le 0 toisc nach bhfuil an roinnt faoi nialas sainithe. Méadaigh an dá thaobh den chothromóid faoi R_{200}.

$$n=R_{200}a+bTR_{200}+cTR_{200}$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$R_{200}a+bTR_{200}+cTR_{200}=n$$

Comhcheangail na téarmaí ar fad ina bhfuil R_{200}.

$$\left(a+bT+cT\right)R_{200}=n$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\left(Tb+Tc+a\right)R_{200}=n$$

Roinn an dá thaobh faoi a+bT+Tc.

$$\frac{\left(Tb+Tc+a\right)R_{200}}{Tb+Tc+a}=\frac{n}{Tb+Tc+a}$$

Má roinntear é faoi a+bT+Tc cuirtear an iolrúchán faoi a+bT+Tc ar ceal.

$$R_{200}=\frac{n}{Tb+Tc+a}$$

Ní féidir leis an athróg R_{200} a bheith comhionann le 0.

$$R_{200}=\frac{n}{Tb+Tc+a}\text{, }R_{200}\neq 0$$

Réitigh do T.

$$\left\{\begin{matrix}T=-\frac{R_{200}a-n}{R_{200}\left(b+c\right)}\text{, }&b\neq -c\text{ and }R_{200}\neq 0\\T\in \mathrm{R}\text{, }&n=R_{200}a\text{ and }b=-c\text{ and }R_{200}\neq 0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh an dá thaobh den chothromóid faoi R_{200}.

$$n=R_{200}a+bTR_{200}+cTR_{200}$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$R_{200}a+bTR_{200}+cTR_{200}=n$$

Bain R_{200}a ón dá thaobh.

$$bTR_{200}+cTR_{200}=n-R_{200}a$$

Comhcheangail na téarmaí ar fad ina bhfuil T.

$$\left(bR_{200}+cR_{200}\right)T=n-R_{200}a$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\left(R_{200}b+R_{200}c\right)T=n-R_{200}a$$

Roinn an dá thaobh faoi cR_{200}+bR_{200}.

$$\frac{\left(R_{200}b+R_{200}c\right)T}{R_{200}b+R_{200}c}=\frac{n-R_{200}a}{R_{200}b+R_{200}c}$$

Má roinntear é faoi cR_{200}+bR_{200} cuirtear an iolrúchán faoi cR_{200}+bR_{200} ar ceal.

$$T=\frac{n-R_{200}a}{R_{200}b+R_{200}c}$$

Roinn n-R_{200}a faoi cR_{200}+bR_{200}.

$$T=\frac{n-R_{200}a}{R_{200}\left(b+c\right)}$$
