Question

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

Answer 1

x-y = 10

x/y = 5/3 --> x = 5y/3.

x-y = 10
5y/3-y = 10
5y-3y = 30
2y = 30
y = 30/2
y = 15.

x = 5y/3
x = 5•15/3
x = 5•5
x = 25.



Verificare : x-y = 25-15 = 10.




J'espère aidé :)

Answer 2

x-y=10
x/y=5/3
x=5y/3

5y/3-y=10
5y-3y=30
2y=30
y=30:2
y=15

x-15=10
x=10+15
x=25
