If you really want an expert to help you, be sure to follow directions and type your __subject__ in the **School Subject** box. Any other words, __including obscure abbreviations__, are likely to delay responses from a teacher who knows that subject well.

d-8/d = d-2/d+10

(d-8)(d+10) = d(d-2)

d^2 + 2d - 80 = d^2 - 2d

4d = 80

d = 20

check:

12/20 = 18/30
