Answer:
7. 7 + 30 = x
8. 37
Step-by-step explanation:
7. The answer is 7+ 30 = x since the x is saying the number of CDs that are there once everything is added up which if you convert the question into words you are saying that the number 7 is being added into 30 which makes the first part of the question 7 + 30. The x would come after the equals sign as the x represents the number of CDs which is 37.
8. The equation from question 7 is 7 + 30 = x so, therefore we are saying that 30 + 7 = the number of CDs.
Hope this makes sense :)
