a=primul numar
b=al doilea numar
(a+b)x3=972
(a-b):2=75
a+b=972:3
a+b=324(prima relatie)
a-b=75x2
a-b=150(a doua relatie)
a+b=324=>a=324-b (acum inlocuiesti in a doua relatie-in loc de a pui 324-b)
324-b-b=150
-b-b=150-324
-2b=-174
-b=-174:2
-b=-87 | x(-1)
b= 87
a+b=324
a+87=324
a=324-87
a=237
Sper ca te-am ajutat!!!
