what would be the answer to this question? The answer i got isn't one of the choices:

Question

(x/x-3) - (x+1/x+3)
I got 1/x+3

Answer 1

What you typed does not make sense. Perhaps you mean:

[ x(x+3) - (x+1)(x-3)] / (x^2-9) ???

[ x^2 + 3x - x^2 +2 x + 3 ] /(x^2-9)

(5x+3)/(x^2-9)

Answer 2

probably meant:

x/(x-3) + (x+1)/(x+3)

and then Damon's steps take over

Answer 3

its x/(x-3) - (x+1)/(x+3)

How did you get that answer?

Answer 4

put it all over a common denominator.

How do you add

2/3 + 5/7 ?

You use the common denominator of 3*7. Do this the same way.
