See a solution process below:

First, subtract #color(red)(3)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#-color(red)(3) + 3 - 7x = -color(red)(3) + 10#

#0 - 7x = 7#

#-7x = 7#

Now, divide each side of the equation by #color(red)(-7)# to solve for #x# while keeping the equation balanced:

#(-7x)/color(red)(-7) = 7/color(red)(-7)#

#(color(red)(cancel(color(black)(-7)))x)/cancel(color(red)(-7)) = -1#

#x = -1#
