See a solution process below:

Explanation:

Add #color(red)(10)# to each side of the inequality to solve for #u# while keeping the inequality balanced:

#-17 + color(red)(10) <= u - 10 + color(red)(10)#

#-7 <= u - 0#

#-7 <= u#

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

#u >= -7#
