x\sqrt{2}=30
Swap sides so that all variable terms are on the left hand side.
\sqrt{2}x=30
The equation is in standard form.
\frac{\sqrt{2}x}{\sqrt{2}}=\frac{30}{\sqrt{2}}
Divide both sides by \sqrt{2}.
x=\frac{30}{\sqrt{2}}
Dividing by \sqrt{2} undoes the multiplication by \sqrt{2}.
x=15\sqrt{2}
Divide 30 by \sqrt{2}.
