  • A
    $4$
  • B
    $6$
  • ✓
    $8$
  • D
    $12$

Answer

Correct option: C.
$8$
$\frac{\text{4x}+8}{2\text{5x}+8}=\frac{5}{6}$
$\Rightarrow6(\text{4x}+8​​)=5(5\text{x}+8)$
$\Rightarrow24\text{x}+48=25\text{x}+40$
$\Rightarrow24\text{x}-25\text{x}=-48\text{x}+40$
$\Rightarrow-\text{x}=-8$
$\Rightarrow\text{x}=8$
