    I am asking you, what does x' represents here? or is that a typo?

    The prime would suggest it's a `derivative of x`. Derivative with respect to what other variable? With respect to y? So it does represent dx/dy?

    let v=y-x then v'=y'-1 -> y'=v'+1 we then have v'+1=(v+2x)/v try solving that, then subbing back in for v in terms of y after integration
