Answer 1

I agree with him the answer is both a and B for c

Answer 2

C. both A and B

Explanation:

The student incorrectly applied the Distributive Property in Step 1 by not multiplying 8 and 7. Then they added 7 to 7 to cancel them out, but subtracted 7 from 75 instead of adding like they did on the other side of the equal sign.
