Question

un numar este cu 40 mai mare decat altul.daca impartim suma numerelor la difereta lor obtinem catul 36 si restul 20.aflati numerele

Answer 1

a=b+40; (a+b)/(a-b)=36, rest 20 => a+b=36(a-b)+20=36a-36b+20 => 35a-37b=-20 => 37b=35a+20 => b=(35a+20)/37 => a=(35a+20)/37+40 <=> 37a=35a+20+1480 <=> 2a=1500 => a=750; b=750-40=710.

Answer 2

X-Y=40
X+Y SUPRA X-Y=36 REST 20
X-Y=40
X+Y=36(X-Y)+20
X-Y=40
X+Y=36*40+20
X-Y=40
X+Y=1460
ADUNAM ECUATIILE
2X /=1500
X=1500 SUPRA 2= 750
Y=X-40=750-40=710
SPER CA TE-AM AJUTAT! :*
