These answers check out perfectly in the three equations.

If there are objections, they should be directed to the problem itself.

Either there are typos in the original statement

If [1] is true, then [3] can__not__be true.

Also, [2] has no solution in real numbers.

The system is inconsistent and has complex roots.

I also agree with your work, I just don't get how we're supposed to answer this question as they are asking for a number (answers are submitted online.) I inputted -3/8 and it said I had the wrong answer.

I've emailed my professor asking about this question.

Thanks for all the help, I'll post back once I have a response from my professor. :)
