le facem pe toate in functie de radu
(r+30)+r+(r+r+r+r)=750
6 * radu=750-30
6 * radu=720
radu=720:6
radu=120
deci fiecare segment din alea inseamna 120
irina=120+30=150
marius=750-(120+150)
marius=750-270
marius=480
sau marius=120+120+120+120=480

Aflam suma partilor egale :
750-30=720
720:6=120 Radu
120+30=150 Irina
120x4=480 Marius
Verificare : 480+150+120=750
