See the entire solution below:

First, add #color(red)(12.3)# to each side of the equation to isolate the #x# term while keeping the equation balanced:

#5x - 12.3 + color(red)(12.3) = 22.7 + color(red)(12.3)#

#5x - 0 = 35#

#5x = 35#

Now, divide each side of the equation by #color(red)(5)# to solve for #x# while keeping the equation balanced:

#(5x)/color(red)(5) = 35/color(red)(5)#

#(color(red)(cancel(color(black)(5)))x)/cancel(color(red)(5)) = 7#

#x = 7#
