Solution

The correct option is B
$\frac{11}{9}$

Given equation is: $3 x + \frac{9}{3} = 5 x + \frac{5}{9}$

$\Rightarrow (5 x - 3 x) = (\frac{9}{3} - \frac{5}{9}) [G r o u p i n g l i k e t e r m s]$

$\Rightarrow 2 x = \frac{27}{9} - \frac{5}{9}$

$\Rightarrow 2 x = \frac{22}{9}$

$\Rightarrow x = \frac{11}{9}$
