    x=(x+1)(x+y)

    \[x=(x+1)(x+y)\]?

    and you want \(y\) right?

    takes two steps' a) divide both sides by \(x+1\) to get \[\frac{x}{x+1}=x+y\]

    then b) subtract \(x\) from both sides to get \(y\) by itself

    oh no dear, just subtract \[\frac{x}{x+1}=x+y\\ \frac{x}{x+1}-x=y\]

    you got \(y\) on one side of the equal sign now right?

    that solves if for \(y\) in other words you are done
