Question

ionel are cu 600 lei mai mult ca adi . Adi are de 3 ori mai putin ca victor , iar victor are cu 200 lei mai putin ca ionel. ce suma are fiecare ?

Answer 1

i=600+a
a=v:3
v=i-200

a=(i-200):2

i=600+(i-200):2 
3i=1800+i-200
2i=1600
i=800 (Ionel)

v=800-200=600 (Victor)

a=600:3=200 (Adi)

Answer 2

200*3=600 victor / 600+200=800 ionel / 600: 3= 200 ady
