Homework Statement
Solve (x+y-1)dx+(y-x-5)dy=0
Homework Equations
The Attempt at a Solution
x=u+h
y=v+k
Therefore
h=-2 and k=3
Therefore
(u+v)du+(v-u)dv=0
[itex]\frac{dv}{du}[/itex]=[itex]\frac{u+v}{u-v}[/itex]
This is where I'm stuck. I can't solve the equation above. I have a feeling I need to rearrange so that I have a function of [itex]\frac{v}{u}[/itex] on the right hand side, but I am unable to rearrange it to attain this.
Any suggestions?
Thank-you
