Ithink it is simplifying, but is that a qualified reason in proofs? i don't think it is the answer the are looking for. use the following problem to answer the question below: given: 3(x – 4) = 33 prove: x = 15  3(x – 4) = 33 given 3x – 12 = 33 a 3x – 12 + 12 = 33 + 12 b 3x + 0 = 45 c 3x = 45 d x = 15 division property of equality what is the reason for d?
