Question: save one group of results

program is：
for t from 10 by 2 to 100 do h := solve({x*y*z = 6*t^3, x-y-z = 0, x+y+z = 6*t}, {x, y, z}); A[(t-8)*(1/2)] := h[1][1] end do
after run:
       {x = 30, y = 20, z = 10}, {x = 30, y = 10, z = 20}
       {x = 36, y = 24, z = 12}, {x = 36, y = 12, z = 24}
       {x = 42, y = 28, z = 14}, {x = 42, y = 14, z = 28}
       {x = 48, y = 32, z = 16}, {x = 48, y = 16, z = 32}
       {x = 54, y = 36, z = 18}, {x = 54, y = 18, z = 36}
       {x = 60, y = 40, z = 20}, {x = 60, y = 20, z = 40}
........................................... and so on

I want to save the result of y from the first solution to a matrix, the result to be （20，24，28，32，36，40....）
but my result is: x=20,x=24....
what can I do ?

help me, Thank you !
