    you can split up the numerator \[\implies \frac{x+1 - 1}{x+1}\] now split up the fraction \[\implies \frac{x+1}{x+1} - \frac{1}{x+1}\] does that give you a hint?

    There are two methods for this: Solve RHS to get LHS.. And other is make some arrangements in LHS to get RHS..

    If you start with x/(x+1) how can you realize that it equals 1-1/(x+1)/

    like i said \[\frac{x}{x+1} \implies \frac{x+1 - 1}{x+1} \implies \frac{x+1}{x+1} - \frac{1}{x+1} \implies 1- \frac 1{x+1}\]

    In the numerator if you add and subtract 1 then there is no effect on the equality...

    Oh, so this is almost like multiple the numerator and denominator by x/x (for example).
