Explicație pas cu pas:
27:[26+(4×a-31):9]-(13-2×2×3)=2
27:[26+(4×a-31):9]-(13-4×3)=2
27:[26+(4×a-31):9]-(13-12)=2
27:[26+(4×a-31):9]-1=2
27:[26+(4×a-31):9]=2 + 1 = 3
26+(4×a-31):9 = 27 : 3 = 9
(4×a-31):9 = 9 - 26 = -17
4×a-31 = -17×9 = -153
4×a= 31 - 153 = -122
a = -122 : 4 = -30,5

1×3-[10+7-(a:27:136)+5×2]:8=0
3 - [17 - (a : 27 : 136) + 10] : 8 = 0
[17 - (a : 27 : 136) + 10] : 8 = 3
17 - (a : 27 : 136) + 10 = 3 × 8 = 24
a : 27 : 136 = 17 + 10 - 24 = 3
a : 27 = 136 × 3 = 408
a = 408 × 27 = 11016
