 Tableau #3 
 x      y      z      s1     s2     r              
 1      0      1      1/5    2/5    0      13      
 0      1      0      -2/5   1/5    0      2       
 1      0      0      0      1      1      28


RREF has to get you to this. When you read the first two lines (the important ones since r=0), you know:

x+z=13
y=2 <-- Isolated for you.

but then you have the last row (r=1) which is the maximized result. So use z-13=x and y=2 in R=28. Get the z. Now get the x. You're done.
