\[ \boxed {\left (12 y-5 x -8\right ) y^{\prime }-5 y=-2 x -3} \]

Solution by Maple

Time used: 0.141 (sec). Leaf size: 33

dsolve((12*y(x)-5*x-8)*diff(y(x),x)-5*y(x)+2*x+3=0,y(x), singsol=all)
 

\[ y \left (x \right ) = -1-\frac {-\frac {5 \left (x +4\right ) c_{1}}{12}+\frac {\sqrt {\left (x +4\right )^{2} c_{1}^{2}+24}}{12}}{c_{1}} \]
