I really need help with this homework problem, the topic is differential equations:
Solve the D.E.
dy/dx = ( x - y - 1 ) / ( x + y + 3 ), by finding h and k so that the substitutions x = u + h and y = v + k transform it into a homogeneous equation dv / du = ( u - v ) / ( u + v )

Good job! That probably is the right answer.. Someone give him a medal

anonymous · Answer

Thank goodness! That means that my senior year of high school was not a complete waste of time!

anonymous · Answer

That makes me wanna revise all the awesome math & physics that i learnt these last few years. Thanks, Bahrom, thank you..
