" b) "(a)/(x-b)+(b)/(x-a)=2

If x=(4ab)/(a+b) then show that (x+2b)/(x-2b)+(x+2b)/(x-2b)=2 .

Find x in terms of a , b and c : (a)/(x - a) + (b)/(x - b) = (2 c)/(x - c) , x - a , b , c

Solve the equations : (1)/(a-b){a^(2)(x-b)-b^(2)(x-a)}=x^(2)

(x)/(b)-(a)/(b)+(x)/(a)-(b)/(a)=2

If x=(4ab)/(a+b) , then the value of (x+2a)/(x-2a)+(x+2b)/(x-2b) is

Solve: a/(x-b)+b/(x-a) = 2(x!=b,a)
