See a solution process below:

Explanation:

First, divide each side of the inequality by #color(red)(3)# to eliminate the parenthesis while keeping the inequality balanced:

#(3(3x + 2))/color(red)(3) < -3/color(red)(3)#

#(color(red)(cancel(color(black)(3)))(3x + 2))/cancel(color(red)(3)) < -1#

#3x + 2 < -1#

Next, subtract #color(red)(2)# from each side of the inequality to isolate the #x# term while keeping the inequality balanced:

#3x + 2 - color(red)(2) < -1 - color(red)(2)#

#3x + 0 < -3#

#3x < -3#

Now, divide each side of the inequality by #color(red)(3)# to solve for #x# while keeping the inequality balanced:

#(3x)/color(red)(3) < -3/color(red)(3)#

#(color(red)(cancel(color(black)(3)))x)/cancel(color(red)(3)) < -1#

#x < -1#
