Réitigh 1115m=11m15cm

$$1115 m = 11 m 15 cm$$

Réitigh do c.

$$\left\{\begin{matrix}c=\frac{1115}{11m_{15}}\text{, }&m_{15}\neq 0\\c\in \mathrm{R}\text{, }&m=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

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

$$11m_{15}cm=1115m$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$11mm_{15}c=1115m$$

Roinn an dá thaobh faoi 11m_{15}m.

$$\frac{11mm_{15}c}{11mm_{15}}=\frac{1115m}{11mm_{15}}$$

Má roinntear é faoi 11m_{15}m cuirtear an iolrúchán faoi 11m_{15}m ar ceal.

$$c=\frac{1115m}{11mm_{15}}$$

Roinn 1115m faoi 11m_{15}m.

$$c=\frac{1115}{11m_{15}}$$

Réitigh do m.

$$\left\{\begin{matrix}\\m=0\text{, }&\text{unconditionally}\\m\in \mathrm{R}\text{, }&m_{15}=\frac{1115}{11c}\text{ and }c\neq 0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain 11m_{15}cm ón dá thaobh.

$$1115m-11m_{15}cm=0$$

Comhcheangail na téarmaí ar fad ina bhfuil m.

$$\left(1115-11m_{15}c\right)m=0$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\left(1115-11cm_{15}\right)m=0$$

Roinn 0 faoi 1115-11m_{15}c.

$$m=0$$
