3 x a + 7 x b = 1 122 l x 4
4 x a + 6 x b = 1 186 l x 3
______________________________
12 a + 28 b = 4 488 ( - )
12 a + 18 b = 3 558
___________________________
/ 28 b - 18 b = 4 488 - 3 558
10 b = 930
b = 930 : 10
b = 93 → al doilea numar
3 x a + 7 x 93 = 1 122
3 x a = 1 122 - 651
a = 471 : 3
a = 157 → primul numar
Raspuns: 157, 93
