x\sqrt{2}=4
Swap sides so that all variable terms are on the left hand side.
\sqrt{2}x=4
The equation is in standard form.
\frac{\sqrt{2}x}{\sqrt{2}}=\frac{4}{\sqrt{2}}
Divide both sides by \sqrt{2}.
x=\frac{4}{\sqrt{2}}
Dividing by \sqrt{2} undoes the multiplication by \sqrt{2}.
x=2\sqrt{2}
Divide 4 by \sqrt{2}.
