275=x_{2}\sqrt{5}
Multiply 55 and 5 to get 275.
x_{2}\sqrt{5}=275
Swap sides so that all variable terms are on the left hand side.
\sqrt{5}x_{2}=275
The equation is in standard form.
\frac{\sqrt{5}x_{2}}{\sqrt{5}}=\frac{275}{\sqrt{5}}
Divide both sides by \sqrt{5}.
x_{2}=\frac{275}{\sqrt{5}}
Dividing by \sqrt{5} undoes the multiplication by \sqrt{5}.
x_{2}=55\sqrt{5}
Divide 275 by \sqrt{5}.
