Answer:

$\frac{20}{369}$

Step-by-step explanation:

$\frac{ 3.4:1.8 - 1 \frac{2}{3} + \frac{7}{9} }{0.918:0.51 + 0.45} =$
$\frac{\frac{34}{18}- \frac{5}{3}+\frac{7}{9} }{18 +\frac{45}{100} } =$
$\frac{\frac{17}{9}-\frac{15}{9}+\frac{7}{9}}{18+ \frac{9}{20} } =$
$\frac{\frac{17-15+7}{9} }{\frac{369}{20} } =$
$\frac{9}{9} } *\frac{20}{369} =$
$\frac{20}{369}$

$x-5+5=3+5\\x=8$

So, solving the equation we get x=8

Option B is correct.
