How do you solve an equation with the variable in the denominator

  1. Mar 8, 2010 #1
    1. The problem statement, all variables and given/known data
    0 = [tex]\sum n_i / (b-a_i)[/tex]
    the summation is goes from i = 1 to k

    the question is to rationalize each term so that the denominator is positive, and then solve for b.

    2. Relevant equations



    3. The attempt at a solution
    i tried to expand the summation and get the factor of b and stuff
    but it didn't work at all
    does anyone know how to solve this summation in terms of b? thanks

    Show us what you tried, and particularly how you expanded the summation. It is after all a finite sum
