Question

Aflati nr a, b, c, d, e, daca : a : b = 6 rest33, a-b = 628, c = d × 4-19, c+d=401,e =a+d

Answer 1

a;b=6+r33    a=6b+33       a=6*119+33=714+33=747   a=747
a-b=628      6b+33-b=628     5b=628-33     b=595:5=119    b=119
c=dx4-19=4d-19     4d=c+19    d=(c+19)/4
c+d=401       c+(c+19)/4=401   4c+c+19=1604    5c=1604-19   c=1585:5
c=317
d=(c+19)/4=317+19)/4=336:4=84
d=84
e=a+d=747+84=831
e=831
