Question

suma a trei numere este 833.Dupa ce se scade din fiecare acelasi numar se obtin nr :218,215,340.aflati numerele initiale

Answer 1

a+b+c=833
a-x=218 =>a=218+x
b-x=215 =>b=215+x
c-x=340 =>c=340+x
Inlocuim in relatia a+b+c=833:
218+x+215+x+340+x=833
773+3x=833
3x=833-773
3x=60
x=60/3
x=20
a=218+x=218+20=238
b=215+x=215+20=235
c=340+x=340+20=360
