Sorry I'm really having difficulties with this one!! I've tried starting off with x5= ...... and working it from there but keep on getting turned around!

I'd imagine that the non-negativity constraint was assumed with all the equations, I intended to indicate x1, x2, x3, x4, x5 >= 0 as the final non-negativity constraint.

You're help has been great though, I honestly appreciate it.
