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