Simple Algebra Question

i came up with 3(x+3)/x+9 but i'm thinking it may just be 2

Find and Simplify:

Hi

3(x+3)/x+9 is OK
What do you mean by "i'm thinking it may just be 2" ?

Hi dempc,

The only thing I'm seeing is

$\displaystyle \frac{4x+3}{x+9}-\frac{x-6}{x+9}$

Is that it? It looks like you might have a picture attached, but I don't see it.

If so, then subtract the numerators and simplify. The denominators are the same.

$\displaystyle \frac{4x+3}{x+9}-\frac{x-6}{x+9}=\frac{4x+3-(x-6)}{x+9}=\frac{4x+3-x+6}{x+9}=\frac{3x+9}{x+9}=\frac{3(x+3)}{x+9}$
