You could just sum them up:
AppropriateType sum_of_solutions (...);
for (unsigned int i=0; i<...; ++i)
sum_of_solutions += solution[i];
Of course, the sum of the solutions equals the solution of a single linear
system with the sum of the right hand sides and the same matrix -- which would
by substantially cheaper to compute.
