How can i solve this equation as it is non-linear and non seperable, i cant use the integrating factor as Q(x) does not exist and i cant seperate so that x and y are separate.

x.(dy/dx)=-3y + 6x

some tips please

thanks..got it now

i used this before and got the wrong answer..

integrating factor is e^3lnx

got answer as y=(3/2)x +c/(x^3)

which is correct

thankyou very much :)
