Question

2√5x+2=2 find the value of x​

Answer 1

Answer:

$\sf \to2 + \sqrt{5x} + 2 = 2$

$\sf \to4 + \sqrt{5x} = 2$

$\sf \to \sqrt{5x} = 2 - 4$

$\sf \to \sqrt{5x} = - 2$

$\sf \to {( \sqrt{5x} )}^{2} = {-2}^{2} [squaring \: both \: sides]$

$\sf \to5x = 4$

$\sf \to x = \frac{4}{5}$

$\sf \to x = 0.8$
