This looks like a totally standard exercise in using the simplex method, so where are you having trouble with it?

Just to get you started, you should introduce "slack variables" u,v,w, to convert the inequalities into equations, namely

The objective equation is , which you write as .

Then you write down the simplex tableau, which is just the matrix of coefficients in these equations, and apply the simplex algorithm.

If it's any help to you, I wrote down a systematic description of the simplex algorithm a few years ago when teaching this stuff. You can find a copy of it here (pdf file). - August 4th 2009, 10:52 AMchella182
My problem is that I don't ever remember being taught this, and it's not in my notes anywhere, so I don't know what the simplex algorithm is or anything. I'll have a look at that .pdf, see if that helps.
