Determinati numerele ( a,b =? ) stiind ca daca a:b=3 rest 4
Plzzzzzz !!!!

Answer 1

a+b=32;
⇒a=3b+4;
⇒3b+4+b=32
⇒4b=28
⇒b=7;
⇒a=3·7+4
⇒a=21+4
⇒a=25;

Answer 2

REZOLVARE:

a + b =32
a : b = 3 (r 4) => a = 3b + 4

inlocuiesti in ecuatia initiala (pe a cu "3b +4") : 
3b+4+b=32
4b +4 =32
4b = 32-4 => 4b = 28 => b = 28 :4
b = 7

a = 3b +4 => a = 3 × 7 +4 => a = 25
