24+x-\sqrt{2}x=18\sqrt{2}
Bain \sqrt{2}x ón dá thaobh.
x-\sqrt{2}x=18\sqrt{2}-24
Bain 24 ón dá thaobh.
\left(1-\sqrt{2}\right)x=18\sqrt{2}-24
Comhcheangail na téarmaí ar fad ina bhfuil x.
\frac{\left(1-\sqrt{2}\right)x}{1-\sqrt{2}}=\frac{18\sqrt{2}-24}{1-\sqrt{2}}
Roinn an dá thaobh faoi 1-\sqrt{2}.
x=\frac{18\sqrt{2}-24}{1-\sqrt{2}}
Má roinntear é faoi 1-\sqrt{2} cuirtear an iolrúchán faoi 1-\sqrt{2} ar ceal.
x=6\sqrt{2}-12
Roinn 18\sqrt{2}-24 faoi 1-\sqrt{2}.
