(Note: As the work is being done independently, it isn't homework, and as such I'm not sure if I need to show what I've done so far. Besides, I don't know much at all about differential equations. I'd have nothing to show.)

[tex]\frac{dy}{dx}=x+y[/tex]

[tex]\frac{dy}{dx}=x-y[/tex]

[tex]\frac{dy}{dx}=y-x[/tex]

And generalizations...

[tex]\frac{dy}{dx}=ax+by[/tex]

[tex]\frac{dy}{dx}=ax-by[/tex]

[tex]\frac{dy}{dx}=ay-bx[/tex]

for constant real a and b.
