okay, I will help you

Answer 2

\[5 \over 2 + x \] plus \[x \over x -4 \]

Answer 3

get common denominators and then add :P

Answer 4

I don't know how to get the common denominators though.

Answer 5

well in this example.. we would just multiply it by (2+x)(x-4)

Answer 6

How do you multiply that?

Answer 7

\[\frac{ 5 }{ 2+x }*\frac{ (2+x)(x-4) }{ 1 }+\frac{ x }{ x-4 }*\frac{ (2+x)(x-4) }{ 1 }\]

Answer 8

So in the first one the 2+x would cancel leaving 5(x-4)
In the second the x-4 would cancel leaving x(2+x)

Answer 9

5(x+4)+x(2+x)
