See a solution process below:

Step 1) Subtract $color(red)(12)$ from each side of the equation to isolate the $x$ term while keeping the equation balanced:

$12 - color(red)(12) - 3x = 6 - color(red)(12)$

$0 - 3x = -6$

$-3x = -6$

Step 2) Divide each side of the equation by $color(red)(-3)$ to solve for $x$ while keeping the equation balanced:

$(-3x)/color(red)(-3) = (-6)/color(red)(-3)$

$(color(red)(cancel(color(black)(-3)))x)/cancel(color(red)(-3)) = 2$

$x = 2$
