Are the x's assumed to be integers?

As there are three unknowns and only two equations, there will not be a unique solution-- but rather multiple solutions.  Also, obviously, since all three variables are specified to be greater than or equal to zero, the solutions may not be integers.

+1 to the Chemical Engineer.

Ironic that when I first studied linear programming it was usinga chem eng problem about mixing oils to make margarine.

There are lots of examples and a few 'solvers' online.

This is homework so can you suggest a next step

Hint you need to do something about the inequality to make the system 'solvable'
