    it is under exact differential equations

    are u sure its not (x+y)/(2x+2y+3) ?

    the take x+y=z and proceed. that is a useful substitution.

    yups but this substitution solves THIS particular sum. if you want a solution with exact differentials i can give u. but u may try this substitution.

    i have but the function will be in z and dy/dx then what should i do

    u will have \[\frac{dz}{dx}=\frac{3z+3}{2z+3}\] Integrate!

    dont understand as dy/dx=z/(2z+3) so did u get dz/dx

    use \[x+y=z \implies 1+\frac{dy}{dx}=\frac{dz}{dx}\] in case u r wondering how i got \[\frac{dz}{dx}\]

    I solved it without using the concept of exact differential equations!
