Question

D au coroana !!!!!!!!!

Answer 1

Răspuns

a:b = cat 4 rest 4 ; a = 4b+4 (teorema impartirii cu rest) inlocuim pe a in diferenta a-b

4b+4-b = 5965 ; 3b = 5965-4 = 5961 ; b = 5961:3 = 1987 ; a = 5965+1987 = 7952 ;

c:b = cat 2 rest 5 ; c = 2b+5 = 2x1987+5 = 3974+5 = 3979 ;

Answer 2

a:b=4 rest 4 => a=b×4+4 }
a-b=5965 => a=b+5965 }=>
b×4+4=b+5965
b×4=b+5965-4
b×4=b+5961
b×4-b=5961
b×3=5961
b=5961/3 =>b=1987
a=1987×4+4 = 7952
c:b=2 rest 5=> c=2×b +5
c=2×1987+5 =3979
a=7952
b=1987
c=3979
