Question

Aflati doua numere x si y stiind ca : x-y =10 si x supra y =5 supra 3

Answer 1

x/y=5/3.   Se mai scrie x/5=y/3=k.             x=5k, y=3k,     5k—3k=10.  2k=10 k=5.        x=5*5=25, y=3*5=15

Answer 2

x - y = 10

x/y = 5/3 ⇒ x = 5y/3

5y/3 - y = 10

5y - 3y = 50

2y = 30

y = 30 : 2

y = 15

x = 10 + 15

x = 25
