4d/(5d-10) + 2d/(10d-20)

I am simply having a difficult time with this one. Could you please just get me started?

1. ASD

Ok, I gave it one more shot. PLEASE let me know if the answer is correct?

10d/[10(d-2)]

2. ASD

Or, should I leave it as 10d/(10d-20), or do I factor out both of the 10d's to come up with -1/20?

10d / 10(d - 2) = d / (d - 2)

You were very close!
