See a solution process below:

Explanation:

Add #color(red)(13)# to each side of the inequality to solve for #r# while keeping the inequality balanced:

#-19 + color(red)(13) >= r - 13 + color(red)(13)#

#-6 >= r - 0#

#-6 >= r#

We can reverse or "flip" the entire inequality to state the solution in terms of #r#:

#r <= -6#
