The general solution (1-2y) DX - (2 + y) dy = 0 Is the general solution of calculus (1-2y) DX - (2 + x) dy = 0

The general solution (1-2y) DX - (2 + y) dy = 0 Is the general solution of calculus (1-2y) DX - (2 + x) dy = 0

Two sides divided by (1-2y) (2 + x)
dy/(1-2y)=dx/(2+x)
Integral gain
-(1/2)ln(1-2y)=ln(2+x)+lnC
y=1/2+A(2+x)^(-2)
