Best ResponseYou've already chosen the best response.2Hmm so it looks like this is separable. Just takes a little bit of work on the right side. Factor by grouping. \[\large y'=1xyy+x\]Factoring a y out of each of the middle terms gives us,\[\large y'=1y(x+1)+x\]We'll rewrite it like this,\[\large y'=(x+1)y(x+1)\]Now we can factor an x+1 out of each term, giving us,\[\large y'=(x+1)(1y)\]

Best ResponseYou've already chosen the best response.2Separating variables gives us,\[\large \frac{dy}{1y}=(x+1)dx\] Understand how to solve it from here? :o
