Differential equation help.

Hey guys, i need some help solving this differential equation.
dw/dt=w(2/5-1/25log(w))
i know you can solve separably by 1/(2w-1/5log(w)) dw=1/5 dt. But i don't think you can solve integrate 1/(2w-1/5log(w)) dw
It's not a linear ODE. Maybe you can make a substitution by letting u=w/t, therefor w=ut and using some chain rule action for dw/dt.
But the point is i'm stuck.
Anyone have an idea?

nvm lol, worked it out.
The substitution needed is u=ln(w)
