Răspuns :
a+b+c=260
a/b=3/2《=》2a=3b
a-b=40=》 a=40+b
inlocuim in raport si aflam b
2(40+b)=3b
80+2b=3b
b=80
a=40+80
a=120
inlocuim in suma si aflam c
120+80+c=260
200+c=260
c=60
Raspuns :
120 , 80 , 60
Explicare pas cu pas :
a,b,c-notare numere
a+b+c=260
a/b=3/2 =>3b=2a
a-b=40 => a=b+40
2*(b+40)=3b => 2b+80=3b => 3b-2b=80 => b=80
a=b+40 => 80+40 =>a=120
c=(a+b+c)-(a+b)
c=260-(120+80)
c=260-200 =>c=60
Cele 3 numere sunt : 120,80,60
