3-%281%2F2%29abs%28r%2B9%29=-11
-%281%2F2%29abs%28r%2B9%29=-11-3
-%281%2F2%29abs%28r%2B9%29=-14....both sides multiply by -1
%281%2F2%29abs%28r%2B9%29=14
abs%28r%2B9%29=14%2F%281%2F2%29
abs%28r%2B9%29=28

solutions
r%2B9=28
r=28-9
highlight%28r=19%29

-%28r%2B9%29=28
-r-9=28
-r=28%2B9
-r=37....both sides multiply by -1
highlight%28r=-37%29
