Could someone help me with math? Dont give me the answer, just help me out

[From: ] [author: ] [Date: 11-09-08] [Hit: ]
..a/x+ 3x/b = b... that is,......
If a/x + 3/bx = b (ab +3 cannot = 0) then x equals...

Seriously how am I even suppose to start this?

does the equation look like this...

a/x + 3x/b = b ... that is, in the 2nd term the x is on top

or like this ...

a/x + 3/(bx) = b ... that is, in the 2nd term, the x is on the bottom

i am going to assume the 2nd one

therefore multiply both sides by bx to get rid of the fraction

ab + 3 = (b^2)x ... so that is why ab + 3 cannot equal zero

so x = (ab + 3) / (b^2)

Sorry .. i asked here and no-one could figure it out.
