See the entire solution process below:

First, subtract $color(red)(4)$ from each side of the equation to isolate the $x$ term while keeping the equation balanced:

$-color(red)(4) + 4 - 3x = -color(red)(4) + 3.5$

$0 - 3x = -0.5$

$-3x = -0.5$

Now, divide each side of the equation by $color(red)(-3)$ to solve for $x$ while keeping the equation balanced:

$(-3x)/color(red)(-3) = (-0.5)/color(red)(-3)$

$(color(red)(cancel(color(black)(-3)))x)/cancel(color(red)(-3)) = 0.1bar6$

$x = 0.1bar6$
