HELP simple question

Answer 1

Answer:

I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.

step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.

Answer 2

I’m gonna guess step 1 (x+7)^2=49 because the math doesn’t make sense on that
