Question

suma a doua nr = 123. daca la primul nr se adauga 83 , iar al doilea 49 , atunci primul nr va fi de 2 ori mai mare decat al doilea . aflati cele 2 nr

Answer 1

a+b=123 => a=123-b
a+83=2(b+49) => 123-b+83=2b+98 =>123+83-98=3b => b= 108/3 =>b=36
a=123-36 => a=87

Answer 2

a + b =123
b)  /....................../......................./..83
a)  /......................../...49
123 +49 + 83 =255
255 : 3 =85 reprezinta o parte
a = 1 x 85  - 49 = 85 -49 =36
b = 2 x 85 - 83 =170- 83 =87
Verificare : a + b = 36 + 87 =123
