```hello, i am interested in arranging a list :
for example ->
\!\(\*
RowBox[{
RowBox[{"k", "=",
RowBox[{"(", GridBox[{
{"1", "0", "0", "0", "0"},
{\(-7.5\), "16", \(-8.5\), "0", "0"},
{"0", \(-8.5\), "18", \(-9.5\), "0"},
{"0", "0", \(-9.5\), "20", \(-10.5\)},
{"0", "0", "0", \(-10.5\), "10.5"}
}], ")"}]}], ";",
RowBox[{"F", "=",
RowBox[{"(", GridBox[{
{"0"},
{"13.75"},
{"11.75"},
{"9.75"},
{"3.875"}
}], ")"}]}], ";"}]\)

In[43]:=
u=Inverse[k].F

Out[43]=
\!\({{1.3010426069826053`*^-14}, {5.21666666666668`},
{8.201960784313735`}, \
{9.636171310629523`}, {10.005218929677142`}}\)

How can I arrange this list to be of ordinary numbers{without the
inner parentheses :
{1.3010426069826053`*^-14, 5.21666666666668`, 8.201960784313735`, \
9.636171310629523`, 10.005218929677142`}
