Question 1006592: Equations with fractions:
Given the following term k = a+b/a-b, which of the following expresses a in terms of b and k?
The answer choice is a = b(k+1)/k-1.
I'm usually pretty good with these, but I'm not getting this one at all.
My attempt: I cross multiply to get k(a-b) = a + b. I then isolate a on the right to get k(a-b) - b = a. From there, I'm stuck. I don't see any way to get to the answer choice.
Thanks for any help.
