\/   20

\sqrt{- 5 x + \frac{3}{20}} = \frac{1}{5}

Simplify

Detail solution

Given the equation

\sqrt{- 5 x + \frac{3}{20}} = \frac{1}{5}

Because equation degree is equal to = 1/2 - does not contain even numbers in the numerator, then
the equation has single real root.
We raise the equation sides to 2-th degree:
We get:

\left(\sqrt{- 5 x + \frac{3}{20}}\right)^{2} = \left(\frac{1}{5}\right)^{2}

- 5 x + \frac{3}{20} = \frac{1}{25}

Move free summands (without x)
from left part to right part, we given:

- 5 x = - \frac{11}{100}

Divide both parts of the equation by -5

x = -11/100 / (-5)

We get the answer: x = 11/500

The final answer:

x_{1} = \frac{11}{500}
