suma a doua numere este 49 iar diferenta este 24,8(3).Aflati numerele

Răspuns :

a-b=24,8(3), a+b=49 ; 24,8(3)= (2483-248) :90;          2235:90/3 ;745/30/5 ; 149/6=a-b

6a-6b=149      6a-6b=149 adunam ecuatiile: 12a =443;a=443/12; inlocuim in a+b=49

a+b=49 x6      6a+6b=294 ;                     443/12+b=49  ; 443+12b=588;12b=558-443=115;  12b=115; b=115/12
