  1. Feb 14, 2016 #1
    1. The problem statement, all variables and given/known data
    dy/dx = (x +y) / (x-y) , i am asked to find the first order differential equation , but the ans i gt is different from the ans given

    2. Relevant equations


    3. The attempt at a solution

    That's already a first order differential equation.

    hotjohn, I think Simon is indirectly chiding you for not following various forum rules, the first of which is to state the problem carefully. You asked "to find the first order differential equation" and Simon is pointing out that that is what you are given. You are also encouraged to use correct English, not expressions like "ans i gt". Finally, the worst thing is to post images instead of typed equations for your solution, making it impossible to edit your work if there are mistakes. Many of the homework helpers will not try to read or respond to such posts.
