See a solution process below:

Explanation:

First, subtract #color(red)(17)# from each side of the inequality to isolate the #w# term while keeping the inequality balanced:

#5 - color(red)(17) <= (6w)/7 + 17 - color(red)(17)#

#-12 <= (6w)/7 + 0#

#-12 <= (6w)/7#

Now, multiply each side of the inequality by #color(red)(7)/color(blue)(6)# to solve for #w# while keeping the inequality balanced:

#color(red)(7)/color(blue)(6) xx -12 <= color(red)(7)/color(blue)(6) xx (6w)/7#

#color(red)(7)/cancel(color(blue)(6)) xx color(blue)(cancel(color(black)(-12)))-2 <= cancel(color(red)(7))/cancel(color(blue)(6)) xx (color(blue)(cancel(color(black)(6)))w)/color(red)(cancel(color(black)(7)))#

#-14 <= w#

To state the solution in terms of #w# we can reverse or "flip" the entire inequality:

#w >= -14#
