54-12:[22-5-(20-a)]+28=76
12:[22-5-(20-a)]=76-28-54=-6
12:[17(-20-a)]=-6
[17-(20-a)]=12:6=2
[17-(20-a)=2
20-a=17-2
20-a=15
a=20-15
a=5
4144-2[(m+n+3)*4]:16+644=6752
4144-2[(m+n+3)*4]:16=6752-644
4144-2[(m+n+3)*4]:16=4108
4144-4108=2[(m+n+3)*4]:16
36=2[(m+n+3)*4]:16
36*16=2[(m+n+3)*4]
2[(m+n+3)*4]=576
(m+n+3)*4=576:2
(m+n+3)*4=288
m+n+3=288:4
m+n+3=72
m+n=72-3
m+n=69
daca nr sunt consecutive, m=n-1
n-1+n=69
2n=70
n=35
m=35-1
n=34
