See a solution process below:

Step 1) Subtract #color(red)(8)# from each side of the equation to isolate the #n# term while keeping the equation balanced:

#3n + 8 - color(red)(8) = 17 - color(red)(8)#

#3n + 0 = 9#

#3n = 9#

Step 2) Divide each side of the equation by #color(red)(3)# to solve for #n# while keeping the equation balanced:

#(3n)/color(red)(3) = 9/color(red)(3)#

#(color(red)(cancel(color(black)(3)))n)/cancel(color(red)(3)) = 3#

#n = 3#
