Réitigh 91x-42y+sqrt{2}=4

$$91 x - 42 y + \sqrt { 2 } = 4$$

Réitigh do x.

$$x=\frac{6y}{13}-\frac{\sqrt{2}}{91}+\frac{4}{91}$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Cuir 42y leis an dá thaobh.

$$91x+\sqrt{2}=4+42y$$

Bain \sqrt{2} ón dá thaobh.

$$91x=4+42y-\sqrt{2}$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$91x=42y+4-\sqrt{2}$$

Roinn an dá thaobh faoi 91.

$$\frac{91x}{91}=\frac{42y+4-\sqrt{2}}{91}$$

Má roinntear é faoi 91 cuirtear an iolrúchán faoi 91 ar ceal.

$$x=\frac{42y+4-\sqrt{2}}{91}$$

Roinn 4+42y-\sqrt{2} faoi 91.

$$x=\frac{6y}{13}-\frac{\sqrt{2}}{91}+\frac{4}{91}$$

Réitigh do y.

$$y=\frac{91x+\sqrt{2}-4}{42}$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain 91x ón dá thaobh.

$$-42y+\sqrt{2}=4-91x$$

Bain \sqrt{2} ón dá thaobh.

$$-42y=4-91x-\sqrt{2}$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$-42y=-91x+4-\sqrt{2}$$

Roinn an dá thaobh faoi -42.

$$\frac{-42y}{-42}=\frac{-91x+4-\sqrt{2}}{-42}$$

Má roinntear é faoi -42 cuirtear an iolrúchán faoi -42 ar ceal.

$$y=\frac{-91x+4-\sqrt{2}}{-42}$$

Roinn 4-91x-\sqrt{2} faoi -42.

$$y=\frac{13x}{6}+\frac{\sqrt{2}}{42}-\frac{2}{21}$$
