    You can turn the problem around so you can see it better.


    9 * z = 75 ..............................z * 9 = 75


    1. Do the opposite of multiplication > division............z * 9 = 75


    2. Divide by nine on both sides


    3. Problem now says...............................z = 75/9 


    Check your answer by putting 75/9 in place of  z  in the problem. Your answer will be 75 = 75.


    You do the other problem the same way.
