=====================================

$\underline{SOLUTION}$ ➡

$2x + \frac{4}{5} x = 8 \\ \\ = > \frac{10x + 4x}{5} = 8 \\ \\ = > \frac{14x}{5} = 8 \\ \\ = > 14x = 40 \\ \\ = > x = \frac{40}{14} \\ \\ = > x = \frac{20}{7}$

$\underline{Checking \: \: result : - }$

$x = \frac{20}{7} \\ \\ Putting \: \: the \: \: value \: \: of \: \: x \: \: in \: \: L.H.S. \: \: of \: \: \\ the \: \: \: equation ,\: \: we \: get ,\\ \\ L.H.S. \: = 2x + \frac{4}{5} x \\ \\ = 2 \times (\frac{20}{7}) + \frac{4}{5} \times (\frac{20}{7 } ) \\ \\ = \frac{40}{7 } + \frac{16}{7} \\ \\ = \frac{56}{7} \\ \\ = 8 \\ \\ = R.H.S.$

$\underline{ANSWER}$ ➡ $\boxed{x = \frac{20}{7}}$
