p\sqrt{5}=5+2\sqrt{5}
Swap sides so that all variable terms are on the left hand side.
\sqrt{5}p=2\sqrt{5}+5
The equation is in standard form.
\frac{\sqrt{5}p}{\sqrt{5}}=\frac{2\sqrt{5}+5}{\sqrt{5}}
Divide both sides by \sqrt{5}.
p=\frac{2\sqrt{5}+5}{\sqrt{5}}
Dividing by \sqrt{5} undoes the multiplication by \sqrt{5}.
p=\sqrt{5}+2
Divide 5+2\sqrt{5} by \sqrt{5}.
