Answer 1

i dont understand what im supposed to do with these kind of problems and the way its set up

Answer 2

Hint: \(\large\frac{x+3}{x - 4} = -\frac{x+3}{4-x}\)

Answer 3

So:

Replacing that, you get

\(-\large\frac{x+3}{4-x} + \frac{x}{4-x} \)

now just add

Answer 4

carefully

Answer 5

I'm basically showing you the stuff books won't show you

Answer 6

3
-----
4 - x ?

Answer 7

Answer 8

its a multiple choice and thats not an option but 3 over (4 - x) is

Answer 9

What are the other options?

Answer 10

The answer is \(-\frac{3}{4-x}\) but even the book can make mistakes

Answer 18

Somehow I goofed up on the negative

Answer 19

Oh, I see

Answer 20

What I posted was also correct

Answer 21

\(-\frac{3}{4-x} = \frac{3}{x-4}\)
