See the entire solution process below:

Step 1) Subtract #color(red)(30)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#4x + 30 - color(red)(30) = 30 - color(red)(30)#

#4x + 0 = 0#

#4x = 0#

Step 2) Divide each side of the equation by #color(red)(4)# to solve for #x# while keeping the equation balanced:

#(4x)/color(red)(4) = 0/color(red)(4)#

#(color(red)(cancel(color(black)(4)))x)/cancel(color(red)(4)) = 0#

#x = 0#
