Réitigh y=3Lk^2

$$y = 3 L k ^ { 2 }$$

Réitigh do L. (complex solution)

$$\left\{\begin{matrix}L=\frac{y}{3k^{2}}\text{, }&k\neq 0\\L\in \mathrm{C}\text{, }&y=0\text{ and }k=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

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

$$3Lk^{2}=y$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$3k^{2}L=y$$

Roinn an dá thaobh faoi 3k^{2}.

$$\frac{3k^{2}L}{3k^{2}}=\frac{y}{3k^{2}}$$

Má roinntear é faoi 3k^{2} cuirtear an iolrúchán faoi 3k^{2} ar ceal.

$$L=\frac{y}{3k^{2}}$$

Réitigh do L.

$$\left\{\begin{matrix}L=\frac{y}{3k^{2}}\text{, }&k\neq 0\\L\in \mathrm{R}\text{, }&y=0\text{ and }k=0\end{matrix}\right.$$

Réitigh do k. (complex solution)
