Answer: Choice C) Harold
Darren is correct because he subtracted c from both sides
Julie is correct because she multiplied both sides by H, and then divided both sides by L
Brenda is correct because she multiplied both sides by r
Harold is not correct. We can see this with a counter example. If A = 7 and h = 1, then the first equation Harold wrote leads to b = 14. Now plug those same values into the second equation and we get h = 2b/A turning into 1 = 2*14/7 and that simplifies to 1 = 4, which is a false statement. This contradiction is one example why the two equations Harold wrote aren't equivalent.
