Consider the differential equation \(y^{2} d x+\left(x-\frac{1}{y}\right) d y=0\). If y (1) = 1, then x is given by
  1. \(1-\frac{1}{y}+\frac{e^{1 / y}}{e}\)
  2. \(4-\frac{2}{y}-\frac{e^{1 / y}}{e}\)
  3. \(3-\frac{1}{y}+\frac{e^{1 / y}}{e}\)
  4. \(1+\frac{1}{y}-\frac{e^{1 / y}}{e}\)

Answer

(D) 1+ 1 y - e^ 1 / y e
