I got -2 and 1 as my answers but Im not sure why 1 isn't included in the answer

These 3 terms have diffrerent denominators.

What do you have to do to add fractions with diff. denoms.?

How would you add 1/3 to 1/7 and then that sum to 1/21?

Answer 3

I have done that part, I just don't know why 1 isn't included in the answer

Do this, please: replace x in the original equation with 1.
Show your work.
Tell me what you observe.
Does your result answer your question?

Answer 5

3/0 is a non real answer, is that why?

Answer 6

Sorry, but I have to disagree with your statement, "3/0 is a non real answer, is that why?"
can you think of a better word to describe 3/0?

Answer 7

You can't divide by 0?

Answer 8

Right. Div by zero is undefined. That is why x=1 is NOT a solution here.
