Răspuns :
a + b = 2003
a + 27 = 3b => a=3b-27
3b - 27 + b = 2003
4b = 1976
b = 494
a = 2003 - 494
a = 1509
a + 27 = 3b => a=3b-27
3b - 27 + b = 2003
4b = 1976
b = 494
a = 2003 - 494
a = 1509
Rezolvare :
Notam cele 2 numere cu :
”x ” ;”y”
scriem datele problemei :
x-27 = 3*y
x = 3b+27(folosim metoda balantei )
x+y = 2003
3y+y+27 = 2003
4y = 2003- 27
y = 494 (am aflat al 2-lea numar)
aflam primul numar :
x = 3*y+27
x = 3*494+27
x =1509
facem verificarea :
x+y= 2003
1509+494 = 2003
