Question

determinat numerele naturale care : a)au suma 103,catul 4 si restul 3

Answer 1

a+b=103
a:b=4 rest 3
a=4b+3
4b+3+b=103
5b+3=103
5b=103-3
5b=100
b=100:5
b=20
a=4x20+3
a=80+3
a=83
proba:83+20=113
           83:20=4 rest 3

Answer 2

a+b=103
a:b=4 rest 3
a=4b+3 (D=i*c+r)
4b+3+b=103
5b=100
b=20
a=83
