Question

a+b+c=369 a:b=4 rest 5, b:c=7 rest 8 afla numerele ! Ma ajuta careva va rog!

Answer 1

A : B = 4 REST 5
A = 4B + 5
B : C = 7 REST 8
B = 7C + 8
A = 4(7C + 8) + 5
A = 28C + 32 + 5
A = 28C + 37
A + B + C = 369
28C + 37 + 7C + 8 + C = 369
36C = 369 - 45
C = 324 : 36
C = 9
B = 7 * 9 + 8
B = 71
A = 28 * 9 + 37
A = 289
