#color(blue)(b >= -8#

Explanation:

Given
#color(white)("XXX")68 >= 60-b#

Add #b# to both sides
#color(white)("XXX")68+b >= 60#

Subtract #68# from both sides
#color(white)("XXX")b >= -8#

Note: you can always add or subtract the same amount to both sides of an inequality without changing the direction or validity of the inequality.
