B = a ori 3 +1
a l-------l
bl---------l----------l-----------l+1   total 89
89-1=88
88:4=22 ( a)
22 ori 3+1=66+1=67 
67+22= 89 total
67:22=3 rest 1 e corect zic eu..

A+b=89
b:a=3 rest 1
b=ax3+1
b=3a+1 acum il inlocuim pe b in a+b=89 
a+3a+1=89
4a=88
a=88:4
a=22
b=3x22+1
b=66+1
b=67

verificare : 22+67=89
