Solution by Maple

Time used: 0.007 (sec). Leaf size: 11

dsolve([x*diff(y(x),x)-2*y(x)= -1,y(0) = 1/2],y(x), singsol=all)
 
\[ y = \frac {1}{2}+c_1 \,x^{2} \]

Solution by Mathematica

Time used: 0.001 (sec). Leaf size: 8

DSolve[{x*D[y[x],x]-2*y[x]== -1,y[0]==1/2},y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \frac {1}{2} \]
