\sqrt{2}+1-\sqrt{2}x-x=0
Subtract x from both sides.
1-\sqrt{2}x-x=-\sqrt{2}
Subtract \sqrt{2} from both sides. Anything subtracted from zero gives its negation.
-\sqrt{2}x-x=-\sqrt{2}-1
Subtract 1 from both sides.
\left(-\sqrt{2}-1\right)x=-\sqrt{2}-1
Combine all terms containing x.
\frac{\left(-\sqrt{2}-1\right)x}{-\sqrt{2}-1}=\frac{-\sqrt{2}-1}{-\sqrt{2}-1}
Divide both sides by -\sqrt{2}-1.
x=\frac{-\sqrt{2}-1}{-\sqrt{2}-1}
Dividing by -\sqrt{2}-1 undoes the multiplication by -\sqrt{2}-1.
x=1
Divide -\sqrt{2}-1 by -\sqrt{2}-1.
