Solution

Given, $30 - 5 x + 2 x = 2 - 2 (1 - x)$

$\Rightarrow$ $30 - 3 x = 2 - 2 + 2 x$ ...[By Distribution Law]

$\Rightarrow$ $30 - 3 x = 2 x$ .

Transposing $x$ terms to one side, we get,
$\Rightarrow$ $- 3 x - 2 x = - 30$

$\Rightarrow$ $- 5 x = - 30$

$\Rightarrow$ $5 x = 30$

$\Rightarrow$ $x = \frac{30}{5} = 6$ .
