How to solve below recurrence relation ?

Question

T(n)=2T(n-1)+n-1, T(1)=1 , n>=2

T(n)=2^kT(n-k)+2^(k-1)(n-(k-1))+2^(k-2)(n-(k-2))+.......+n

Now k=n-1

T(n)=2^(n-1)(1)+2^(n-2)(2)+2^(n-3)(3)+.......+2^(n-n)(n)

T(n)=2(n)[ 1/1 + 2/2⁽²⁾ +3/2 ⁽³⁾ + 2/ 2⁽⁴⁾ +....]  + n

Now I am struck at this point how to proceed from here ?
