Math hmwk help

Hey guys, I've been stuck on this one problem for god noes why. I've done harder questions than this before, but I can't seem what the common denominator would be to solve it out.

Solve by any method:
6/x + 6/x+9 = 1

Thanks for the help~

[quote=FrostyGun]You mean unplugging what I got back into the equation? If so, yes I did, but it didn't work.

@HolyDragon

Thanks. I got it now, I was confused at the x+9 part when I had to multiply, I kept trying to cancel the x out, but now I remember you can't since it's seperated by a + sign. And yes I do, I looked there but couldn't figure it out.[/quote]

6/(x) + 6/(x+9) = 1

Let's go one step at a time.
Multiply by x.

6 +6x/(x+9) = x

Now (x+9)

(6x + 54) + 6x= x^2+9x
Solve.
