solve [ { e^[-2sqrt(x)] / sqrt(x) } - {y / sqrt(x)}] [dx/dy] = 1 [x is not 0]
here there is only one term in y
so we have to rearrange the equation in the form
[dy/dx] + Py = Q
identify the values of P and Q
find the integrating factor e^[integral of P]
and use in the solution
y[integrating factor] = integral of [Q*integrating factor] + C
