Răspuns

Explicație pas cu pas:

A+B+C=297

A:B=2 REST 25

A:C=11 REST 8

_____

A=2•B+25

A=11•C+8

_______

2B=A-25

11C=A-8

______

B=(A-25):2

C=(A-8):11

_______

A+(A-25):2+(A-8):11=246 || •22

22A+(A-25)•11+(A-8)•2  = 246•22

22A + 11A - 25•11 + 2A - 8•2 = 246•22

22A + 11A - 275 + 2A - 16 = 5412

22A + 11A + 2A = 5412 + 275 + 16

35A = 5703

A = 5703/35

B = (5703/35 - 25)/2 = (5703 - 875) / 70 = 4828/70 = 2414/35

C = (5703/35 - 8)/11 = (5703 - 280)/385 = 5423/385
