ps to put it in standard form
replace the last 2 equations by
1x1 + 1x2 + 1x3 + 1x4 + 1x5 + 1x6 + 1x7 + 1x8 + 1x9 + 1x10 + 1x11 + 1x12 - x14 <=1
the objective function to
Minimize p =

Your solver is fussy about the format at start of each equation. I got it to "work" for below but basically the problem is too big. You need to find a better solver. You may have to download one. All the online ones are the same code as far as I can see.
