Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain 211x^{2} ón dá thaobh. Is ionann rud ar bith a dhealaítear ó nialas agus a shéanadh.

$$2012xy+222yz+2013x+2023y+9933=-211x^{2}$$

Bain 2013x ón dá thaobh.

$$2012xy+222yz+2023y+9933=-211x^{2}-2013x$$

Bain 9933 ón dá thaobh.

$$2012xy+222yz+2023y=-211x^{2}-2013x-9933$$

Comhcheangail na téarmaí ar fad ina bhfuil y.

$$\left(2012x+222z+2023\right)y=-211x^{2}-2013x-9933$$

Roinn an dá thaobh faoi 2012x+222z+2023.

$$\frac{\left(2012x+222z+2023\right)y}{2012x+222z+2023}=\frac{-211x^{2}-2013x-9933}{2012x+222z+2023}$$

Má roinntear é faoi 2012x+222z+2023 cuirtear an iolrúchán faoi 2012x+222z+2023 ar ceal.

$$y=\frac{-211x^{2}-2013x-9933}{2012x+222z+2023}$$

Roinn -211x^{2}-2013x-9933 faoi 2012x+222z+2023.
