Qing,
    For minimization of linear functions with linear constraints, see the
function ConstrainedMin:

In[413]:=
ConstrainedMin[2 x - 3 y, {x + y < 10, x - y > 2, x > 1}, {x, y}]

Out[413]=
{0, {x -> 6, y -> 4}}

In[416]:=
ConstrainedMin[2 x - 3 y, {x + y == 12, x - y > 2, x > 1}, {x, y}]

Out[416]=
{-1, {x -> 7, y -> 5}}
