Din b>c cu 22 rezulta ca b=c+22
Daca d=70 ne da ca a=c+70
Le inlocuim in prima relatie
c+70+c+22+c+70=264
3c+162=264
3c=264-162
3c=102
c=102:3
c=34
a=34+70=104
b=34+22=56

A+b+c+d=264
a=c+d
d=70
b=c+22
c+d+c+22+c+70=264
3c+70+22+70=264

3c+162=264
3c=102,c=34
b=34+22=56
a=34+70=104
104+56+34+70=264
