Question 90403


            14/(x^2-1)+1/(x-1)=3/(x+1)
            
            14/(x+1).(x-1)+1/(x-1) = 3/(x+1)

               [14+1(x+1)]/(x+1).(x-1) = 3/(x+1)
                 [14+x+1]/(x-1) = 3      (cancel (x+1) on both sides) 

                   x+15 = 3(x-1)
                      15+3 = 3x-x
                         18 = 2x
                          x = 18/2 = 9
            The value of x = 9 is th solution for the eq'n
