Homework Statement



Solve the initial value problem: y+(3x-xy+2)dy/dx = 0 , y(1)=1

I couldn't separate with y as a dependent variable, so I made x the dependent variable and I get this: dx/dy= x(1-2/y)-(2/y),
in linear standard form: dx/dy+(3/y - 1)x = -2/y.

The Attempt at a Solution



You can see that I attempted the solution. I'm just wondering if I performed the steps correctly and if the answer is correct.

Did you try substituting the solution back into the given equations?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
