Answer 1

4b+b+b+7+8=369    6b=369-15    6b=354      b=354:6    b=59     a=4x59+7   a=243    59+243+c=369     302+c=369   c=369-302     c=66

Answer 2

a+b+cd=369
a:b=4 rest 5⇒  a=4b+5     
B:c=7 rest 8⇒b=7c+8

Inlocuim
in loc de a scriem 4*7c+4*8+5
in loc de b scriem 7c+8
  
28c+32+5+7c+8+c=369
36c+45=369
36c=324  c=324:36
c=9
a=4*7*9+4*8+5
a=286
b=7*9+8
b=71
