Answer:
x>4
Step-by-step explanation:
 
        
             
        
        
        
11. 6 + 5 * 2 + (-3)
      6 + 10 - 3
      16 - 3
       13 <==
12. 67 + 84 - 12 * 4 / 16
      67 + 84 - 48/16
      67 + 84 - 3
      148 <==
13. -5 * -6 - 25/5 - 2
      30 - 5 - 2
       23 <==
14. 18 - (9 + 3) + 2^3
       18 - 12 + 8
        14 <==
15. -24 / -6 * 2
       4 * 2
       8 <==
16. 8 [ (26 + 10) - 4(3 + 2)]
      8 [ (36 - 4(5)]
      8 [ 36 - 20 ]
      8 [ 16 ]
        128 <==
17. 6 * 3 / 9 * 2 + 1
       18/9 * 2 + 1
        2 * 2 + 1
        4 + 1
        5 <==
18. (9 - -4)(-8 - -7)
      (9 + 4)(-8 + 7)
       13 * -1
       -13 <==
        
             
        
        
        
The answer would be 5x+5y
