See entire solution process below:

Explanation:

To solve this inequality we need to divide each side of the inequality by #color(blue)(-7)# to solve for #f# while keeping the equation balanced.

However, whenever you multiply or divide an inequality by a negative term you must reverse the inequality:

#-7f > 5 ->#

#(-7f)/color(blue)(-7) color(red)(<) 5/color(blue)(-7)#

#(color(blue)(cancel(color(black)(-7)))f)/cancel(color(blue)(-7)) color(red)(<) -5/7#

#f < -5/7#
