Question

află numerele a,b,c stiind că: a+b+c=908, a+b=722 iar b+c=483

Answer 1

a+b+c=908
a+b=722
b+c=483
____________
se inlocuieste relatia a+b in relatia a+b+c , de unde
722+c=908 , de unde c=908-722=186
b+186=483 , de unde b=297
a+297=722 , de unde a=435

Answer 2

a+b+c = 908
a+b=722
b+c =483
722 + c = 908
c=908-722
c=186

a+ 483 = 908
a=908-483
a=425
a+b=722
425 +b =722
b=722-425
b=297
V: a+b+c = 425 + 297+186= 908(adevarat)
