See a solution process below:

First, subtract #color(red)(1)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#-9x + 1 - color(red)(1) = -80 - color(red)(1)#

#-9x + 0 = -81#

#-9x = -81#

Now, divide each side of the equation by #color(red)(-9)# to solve for #x# while keeping the equation balanced:

#(-9x)/color(red)(-9) = (-81)/color(red)(-9)#

#(color(red)(cancel(color(black)(-9)))x)/cancel(color(red)(-9)) = 9#

#x = 9#

#x=9#

Begin by subtracting #1# from both sides:

#-9xcancel(+1color(red)(-1))=-80color(red)(-1)#

#-9x=-81#

Divide both sides by #-9#

#cancel(-9)/cancelcolor(red)(-9)x=(-81)/color(red)(-9)#

#x=9#
