Question: Combine two solutions from LPSolve and take the value

Dear All,
Perhaps my question is basic question, but I want to know more about LPSolve
Is it possible to join 2 solutions from different LPSolve?

For example, I have 2 solutions,
Sol[1] := [72.011122301, [t[4] = -.500000000000000, t[13] = .500000000000000, x[1, 4] = 1, x[1, 13] = 0, x[4, 1] = 0, x[4, 13] = 1, x[13, 1] = 1, x[13, 4] = 0]];
Sol[2] := [53.128387340, [t[6] = -2.00000000000000, t[7] = 0., t[8] = -.999999999999999, x[1, 6] = 1, x[1, 7] = 0, x[1, 8] = 0, x[6, 1] = 0, x[6, 7] = 0, x[6, 8] = 1, x[7, 1] = 1, x[7, 6] = 0, x[7, 8] = 0, x[8, 1] = 0, x[8, 6] = 0, x[8, 7] = 1]].

What I want to achieve is following:

(1) eliminating t variable and join those solution (all values of x). Thus, I got [ x[1, 4] = 1, x[1, 13] = 0, x[4, 1] = 0, x[4, 13] = 1, x[13, 1] = 1, x[13, 4] = 0,x[1, 6] = 1, x[1, 7] = 0, x[1, 8] = 0, x[6, 1] = 0, x[6, 7] = 0, x[6, 8] = 1, x[7, 1] = 1, x[7, 6] = 0, x[7, 8] = 0, x[8, 1] = 0, x[8, 6] = 0, x[8, 7] = 1]].
(2) Extracting the value of X. I know that sol[1][2] indicates the values of right hand side. But I want to get the value of each of x in sequence.
for example: I can get x[1,2]=1, x[1,8]=0, x[7,1]=0 and so on.
In this case, Maybe I can use
eval(x[1,8],sol[1]) for specific x.
But is there any nice way to get all values of x with some procedures?
