Question

La o florarie s-auadus 435 tranafiri albi si rosii.Trandafirii rosii sunt cu 24 mai mult decat jumatatea celor albi.

Answer 1

Suma este 435 deci calculam suma partilor egale:
 435-24=411 suma partilor egale
 411:3=137 o parte
 137x2=274 ( Albi )
 137+24=161 (Rosii )
Verificare : 274+161=435

Answer 2

a+r=435
⇒r=24+a/2;
⇒a+24+a/2=435
⇒a+a/2=435-24
⇒a+a/2=411
⇒2a/2+a/2=411
⇒3a/2=411
⇒a=2·411/3
⇒a=2·137
⇒a=274[trandafiri-albi];
⇒r=24+274/2
⇒r=24+137
⇒r=161[trandafiri-rosii];
