Math Help

[hobosexual]

Sorry, I know this isn't exactly an interesting topic but I do need someone to help me out with a probelm.

The problem is:

Solve x = pm(1/y + a/bd) for d

I did the problem twice and both times I got an answer of

d = apmxy/bxy-1bpmx

I'm pretty sure I'm going about it the right way but it would be nice if a few others who are good at math could do the problem for me and see if I made any stupid mistakes as I have no way of checking myself and I would really like a 100 on my honors Advanced Math test tommorow.

the answer is d=yamp/(xby-mbp)

did it in my head, 99% sure

Ok but could you show your work? That looks better than mine but it would help if I knew how you got it.

x = pm(1/y + a/bd)
x/pm = 1/y + a/bd
x/pm - 1/y = a/bd
(xy-pm)/pmy = a/b * 1/d
d= (a/b)*[pmy/ (xy-pm)]
= yamp/ (xby-mbp)
