map2 helps you

If you think about eval([x,y],{x=0,y=-1}) giving [0,-1], then you can work this up with map2 to give what you want:

q:={x = 0, y = -1}, {x = 3/4, y = -7/16}:

map2(eval,[x,y],[q])[];

gives

[0,1],[3/4,-7/16]

as required. This works for any number of solutions returned by solve.

or seq

I would have done this with seq, as follows:

q:={x = 0, y = -1}, {x = 3/4, y = -7/16};
                                       /    3      -7\ 
                     {y = -1, x = 0}, { x = -, y = -- }
                                       \    4      16/ 
seq( eval([x,y],p), p=[q] );
                                       [3  -7]
                              [0, -1], [-, --]
                                       [4  16]
