See the entire solution process below:

Explanation:

Step 1) Subtract #color(red)(5)# to each side of the equation to isolate the #x# term while keeping the equation balanced:

#-4 - color(red)(5) = 5 - 3x - color(red)(5)#

#-9 = 5 - color(red)(5) - 3x#

#-9 = 0 - 3x#

#-9 = -3x#

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

#(-9)/color(red)(-3) = (-3x)/color(red)(-3)#

#3 = (color(red)(cancel(color(black)(-3)))x)/cancel(color(red)(-3))#

#3 = x#

#x = 3#
