a. Solve a – 9 = 20

b. Solve b – 9 > 20

c. How is solving the equation in (a) similar to solving the inequality in (b)?

d. How are the solutions different?


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

    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
