#b < 13#

First, add #9.2# to each side of the inequality to isolate the #b# term and keep the inequality balanced:

#1.3b - 9.2 + 9.2 < 7.7 + 9.2#

#1.3b + 0 < 16.9#

#1.3b < 16.9#

Next, divide each side of the equation by #1.3# to solve for #b# while keeping the inequality balanced:

#(1.3b)/1.3 < 16.9/1.3#

#(cancel(1.3)b)/cancel(1.3) < 13#

#b < 13#
