Question

Aflati nr x si y , stiind ca sunt d.p cu 2 si 3 si ca diferenta lor este 15.

Answer 1

x/2=y/3=k
x=2k
y=3k
3k-2k=15
k=15
x=30
y=45

Answer 2

x/2=y/3 si y-x=15
y=3x/2
3x/2 -x=15
x/2=15
x= 30
y= 3*30/2= 3*15 = 45
--------------------------------------
Met II: x/2=y/3=k
x=2k
y=3k
y-x=3k-2k=15
k=15
x=2k= 30
y=3k= 45.
