I don't know how to do this i forgot ... could u help (Steve, or Mrs.Sue, or Writeteacher plz help)

Answer 1

in both cases, add 9 to both sides

a = 29
b>29

In the first case, 29 is the only solution
In the second case 29 is not a solution but anything to the right of 29 on a number line is a solution, even 29.00001

Answer 2
