DSolve[4 + 2*x - y[x] + (7 + x + 2*y[x])*Derivative[1][y][x] == 0,y[x],x]
 

\[\text {Solve}\left [2 \log \left (\frac {4 \left (x^2+y(x)^2+4 y(x)+6 x+13\right )}{5 (x+3)^2}\right )+2 \tan ^{-1}\left (\frac {y(x)-2 (x+2)}{2 y(x)+x+7}\right )+4 \log (x+3)+5 c_1=0,y(x)\right ]\] Maple : cpu = 0.096 (sec), leaf count = 32

dsolve((2*y(x)+x+7)*diff(y(x),x)-y(x)+2*x+4 = 0,y(x))
