To find the general solution of the differential equation y '= (XY + y) / (x + XY), I don't know how to calculate y + ln | y | = x + ln | x | + C This is the answer Ye ^ y = Xe ^ X

To find the general solution of the differential equation y '= (XY + y) / (x + XY), I don't know how to calculate y + ln | y | = x + ln | x | + C This is the answer Ye ^ y = Xe ^ X

e^(y+ln|y|)=e^(x+ln|x|+C)
e^y*e^ln|y|=e^x*e^ln|x|*e^C
|y|e^y=|x|e^x*e^C
ye^y=±e^C*xe^x
Ye ^ y = C * Xe ^ x (where C is equal to ± e ^ C of the previous row)
