If $$\frac{x}{a+b}+1=\frac{x}{a-b}+\frac{a-b}{a+b}$$, then value of $$x$$ is
Expression : $$\frac{x}{a+b}+1=\frac{x}{a-b}+\frac{a-b}{a+b}$$
=> $$\frac{x}{a+b}-\frac{x}{a-b}=\frac{a-b}{a+b}-1$$
=> $$\frac{x(a-b)-x(a+b)}{(a+b)(a-b)}=\frac{(a-b)-(a+b)}{a+b}$$
=> $$\frac{-2bx}{a-b} = -2b$$
=> $$x = (a-b)$$
=> Ans - (C)
