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.
