`3x . [8^{2} - 2 . (2^{5} - 1)] = 2022`
$\Rightarrow$ `3x . [64 - 2 . (32 - 1)] = 2022`
$\Rightarrow$ `3x . [64 - 2 . 31] = 2022`
$\Rightarrow$ `3x . [64 - 62] = 2022`
$\Rightarrow$ `3x . 2 = 2022`
$\Rightarrow$ `3x = 2022 : 2`
$\Rightarrow$ `3x = 1011`
$\Rightarrow$ `x = 1011 : 3`
$\Rightarrow$ `x = 337`
$\text{Vậy}$ `x = 337`
