2x=15-6y

Bain 6y ón dá thaobh.

\frac{2x}{2}=\frac{15-6y}{2}

Roinn an dá thaobh faoi 2.

x=\frac{15-6y}{2}

Má roinntear é faoi 2 cuirtear an iolrúchán faoi 2 ar ceal.

x=\frac{15}{2}-3y

Roinn 15-6y faoi 2.

6y=15-2x

Bain 2x ón dá thaobh.

\frac{6y}{6}=\frac{15-2x}{6}

Roinn an dá thaobh faoi 6.

y=\frac{15-2x}{6}

Má roinntear é faoi 6 cuirtear an iolrúchán faoi 6 ar ceal.

y=-\frac{x}{3}+\frac{5}{2}

Roinn 15-2x faoi 6.
