9x-\sqrt{8}=0
Combine x and 8x to get 9x.
9x-2\sqrt{2}=0
Factor 8=2^{2}\times 2. Rewrite the square root of the product \sqrt{2^{2}\times 2} as the product of square roots \sqrt{2^{2}}\sqrt{2}. Take the square root of 2^{2}.
9x=2\sqrt{2}
Add 2\sqrt{2} to both sides. Anything plus zero gives itself.
\frac{9x}{9}=\frac{2\sqrt{2}}{9}
Divide both sides by 9.
x=\frac{2\sqrt{2}}{9}
Dividing by 9 undoes the multiplication by 9.
