See a solution process below:

Step 1) Add #color(red)(12.6)# to each side of the equation to isolate the #x# term while keeping the equation balanced:

#4x - 12.6 + color(red)(12.6) = 15.4 + color(red)(12.6)#

#4x - 0 = 28#

#4x = 28#

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) = 28/color(red)(4)#

#(color(red)(cancel(color(black)(4)))x)/cancel(color(red)(4)) = 7#

#x = 7#
