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

What do you mean its not linear? Note that $\displaystyle x\frac{\,dy}{\,dx}=-3y+6x \implies \frac{\,dy}{\,dx}+\frac{3}{x}y=6$ is of the form $\displaystyle \frac{\,dy}{\,dx}+P(x)y=Q(x)$, which is clearly linear...
Can you take it from here and use the integrating factor?
