Un mester popular a confectionat intru-n an 480 de fluiere,ocarine si viori.Cate instrumente de fiecare fel a confectionat meste
Marta_Voda [28]

Answer:

138 fluiere, 158 ocarine, 184 viori

Step-by-step explanation:

given:

(1) fluiere + ocarine +viori = 480

(2) fluiere + ocarine =296

(3) ocarine + viori =342

din ecuatia (3) avem: viori= 342-ocarine

din ecuatia(2) avem : fluiere= 296-ocarine

in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480

296-ocarine +ocarine+ 342-ocarine  =480

296+342-480 = ocarine =158

viori = 342-158 = 184

fluiere = 296-158 = 138
