daca x+y = 162
y +z = 354
-----------------------------------------
le scadem y +z - x - y = 354 - 162
z - x = 192
cu x +z =408
z -x =192
-----------------------------
2z= 408 +192 ; 2z= 600 ; z =300
x = 408 - 300 = 108
y = 162 - x = 162 - 108 = 54
y +z = 354
-----------------------------------------
le scadem y +z - x - y = 354 - 162
