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#
