```Hi. I'm wondering how to solve a system of inequalities. I've got five
inequalities in three variables that I'd like to find plausible limits
for. Is there any way to do this within mathematica? Thanks so much. BTW:
I need fairly explicit instructions. My first exposure to Mathematica was
this evening and I'm not even sure how to solve a single inequality. I try
this, but get:
In[15]:=
Solve[2 x^2 + x > 3, x]
2
Solve::eqf: Auxiliary[x + 2 x  > 3]
is not a well-formed equation.
Out[15]=
2
Solve[x + 2 x  > 3, x]

Clearly, I have no idea what I'm doing. Please advise via email. Thanks.
