    Hmm so it looks like this is separable. Just takes a little bit of work on the right side. Factor by grouping. \[\large y'=1-xy-y+x\]Factoring a -y out of each of the middle terms gives us,\[\large y'=1-y(x+1)+x\]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,\[\large y'=(x+1)(1-y)\]

    Separating variables gives us,\[\large \frac{dy}{1-y}=(x+1)dx\] Understand how to solve it from here? :o
