Step 3. This leads to the influence of the idea that 7d is subtracted by 16.
Step 4. This concludes that the answer is 7d - 16.
Question B:
Step 1: The product of 7 concludes that 7 is alone.
Step 2: The separation of and shows that the part after and is together.
Step 3: If it is together, we can conclude it goes in parentheses.
Step 4: If it is in parentheses, it means the number 7 is being distributed.
Step 5: This concludes the answer is 7(d - 16).
